直流无刷电机（BrushlessDCmotor）
直流无刷电机（Brushless DC motor）0 IntroductionIn the development of the smart car, an important part is that the smart car can adjust the speed and direction of the vehicle independently according to the surrounding obstacles. DC motor speed control system designed in this paper is an important part of the intelligent car, DC motor speed control system is mainly composed of S3C44B0X processor and motor drive chip L298N, the main function is the two wheel drive car, adjust the vehicle speed, by changing the two wheel speed adjustment direction.1 Hardware DesignDesigned by ARM, the ARM processor with RISC architecture has strong performance, low power consumption, small size, and supports Thumb (16 bit) /ARM (32 bit) double instruction set, and the instruction execution speed is fast. At present, ARM series microprocessor has occupied more than 75% market share in the 32 bit RISC embedded products. Especially ARM7TDMI series is the most widely used, and its cost performance is also the highest.1.1 brief introduction of S3C44B0XS3C44B0X is a 16/32 bit RISC processor based on the ARM7TDMI kernel introduced by Samsung. This processor provides a wide range of on-chip peripherals that greatly reduce configuration of components other than the processor in system circuitry. The S3C44B0X has 6 16 bit timers, each of which can operate in either an interrupt mode or a DMA mode. Timers 0, 1, 2, 3, 4 have thePWM function, and timer 5 is an internal timer. Timer 0 and 1, 2 and 3, 4 and 5 respectively, sharing a 8 bit prescaler (Prescaler), the scope of the prescaler value is 0 - 255, three prescaler value through the TCFG0 register set; the timer 0, 1, 2, 3 each have a 5 different frequency signals (1/2, 1/4, 1/8, 1/16, 1/32) clock divider (Divider), timer 4 and 5 are respectively provided with a 4 frequency signal (1/2, 1/4, 1/8, 1/16) clock divider. The segmentation values of the 6 timers are set by register TCFG1.Timer input clock frequency = MCLK/Prescaler/Divider. Among them, MCLK = 60MHz is the dominant frequency of the system.1.2 hardware implementationIn order to improve the system efficiency and reduce power consumption, the power amplifier circuit is based on the bipolar H bridge pulse width modulation (PWM) integrated circuit L298N. L298N SGS is the product of the company, including high voltage and high current driver two H bridge, receiving standard TTL logic level signal to drive a 46 volt, 2 amp motor below the working temperature range from - 25 degrees to 130 degrees. A schematic diagram of a H bridge within it is shown in figure 1. The EnA is a control enable terminal that controls the stop of the motor between the OUTl and the OUT2, and the IN1 and IN2 pins are connected to the control level to control the steering of the motor between the OUTl and the OUT2. When the enable terminal EnA is valid, the IN1 is low, the IN2 is high, the transistor 2, the 3 are connected, and the 1 and 4 are cut off, the motor reverses. When the IN1 and IN2 levels are the same, the motor stops.Another H bridge works the same as above. The motor stop between OUT3 and OUT4 is controlled by EnB, and the steering of the motor between OUT3 and OUT4 is controlled according to the input level of IN3 and IN4 pins.Since the S3C44B0X itself contains 5 PWM outputs, the direct output control signal can be applied to the L298N without additional circuitry. The schematic diagram of the system is shown in figure 2. In the system, timers 1 and 2, which work in interrupt mode, are selected as timers for generating PWM. Through programming, set the I / O port, PE4 and PE5 as the timer 1, 2 output PWM port, access to the L298N EnA and EnB port, according to the timer 1, 2 output PWM frequency control two DC motor speed. PE6 is set to output port, connected to IN1 and connected to IN2 via a reverser; similarly, PE7 is also set to output port, access to IN3, and access to IN4 via a reverse device. By accessing the reverser, the IN1 and the IN2, IN3 and IN4 will not be at the same high or low level, i.e., the motor will not stop because the IN1 and IN2, the IN3 and the IN4 levels are the same.The stop operation of the motor can be achieved by modulating the pulse width to 0, i.e., the duty cycle is 0, or the bit of the timer is turned off. Thus, only one signal PE6 can control the state of IN1 and IN2, and PE7 controls the state of IN3 and IN4, thus reducing the control signals of the system and simplifying the system to a certain extent. In order to ensure the normal work of the L298N driver chip, but also to join in with the DC motor of four diode with current in the motor back EMF generated by the shunt to ground or power, in order to avoidreverse electromotive force damage to L298N.2 software design of the system2.1 timer operation modeIn S3C44B0X, each timer has an inverted timer that drives the 16 bit countdown register TCNTn via the timer clock source. Before the timer starts, write an initial value to the timer count buffer register (TCNTBn), which is loaded into the countdown timer TCNTn when the timer is started. In the timer comparison buffer register (TCMPBn), an initial value is also written. The runtime is used to load into the comparison register TCMPn and compare with the value of the countdown timer TCNTn. When you start the system, you need to load the values of the two buffers, TCMPBn and TCNTBn, into TCMPn and TCNTn by setting the manual refresh bit. The application of these two buffers, i.e., double buffers, of TCMPBn and TCNTBn, allows the timer to produce a stable output at the same time as frequency and duty cycle. The general steps to start the timer are as follows:1) writes the initial value to TCNTBn and TCMPBn.2) set the automatic reload bit of the corresponding timer3) set the manual update bit for the corresponding timer, and the counter is set to the off state4) setting the start bit of the corresponding timer to start the timer and clearing the manual update bit at the same time.At this point, the timer TCNTn starts counting backwards. When the TCNTn has the same value as the TCMPn, the logic level of the TOUTn is changed from low to high. When the counter TCNTn reaches 0, a timer interrupt request is generated, informing the CPU that the timer operation has been completed. At this point, if the auto reload control bit enable, the value of the TCNTBn is automatically loaded into the TCNTn register and the next operation cycle is started. If the timer is stopped by clearing the timer, enabling bits, etc., the count value will not be automatically overloaded.2.2 modulation PWMPulse width modulation (Pulse Width Modulation PWM) means that the basic cycle of the output signal is fixed, and the output power is controlled by adjusting the size of the working cycle in the basic cycle. For a timer, when the frequency of the input clock source is generally unchanged, namely TCFG0 (timer prescaler value) and TCFG1 (timer segmentation value) value after setting no change. This provides a stable clock source for PWM. The speed of the motor is proportional to the voltage at both ends of the motor, and the voltage at both ends of the motor is proportional to the duty cycle of the control waveform. Therefore, the speed of the motor is proportional to the duty cycle, and the larger the duty ratio, the faster the motor is turned. In the system, the PWM pulse frequency is decided by TCNTBn, and the PWM pulse width value is decided by the value of TCMPBn, and the duty cycle is TCMPn/TCNTn. If you want to make the motor speed down, a relatively low output value of PWM pulse width is obtained, can reduce the value of TCMPBn; to makethe motor speed increase, the output of a higher PWM value, can increase the value of TCMPBn. Because of the characteristics of the double buffer, a PWM cycle TCMPBn value by ISR (interrupt service routine) or other means in the current cycle of low level PWM at any point that is written, can be blocked by re setting the value of TCMPBn to change the motor speed in the program. The value of the buffer TCMPBn and TCNTBn is not necessarily equal to the value of the TCMPn, TCNTn of this cycle, but must be the value of the next cycle of TCMPn and TCNTn.2.3 program codeThe application in this article is in ADS1.2 development environment, cross compiled, downloaded to Flash running. Program code (take timer 1 as an example):/ / initialize portVoid, Init_PortE (){RPCONE=0x5a00; / / define I/O port //PE4, PE5, PE6, PE7 / / functionRPUPE=0xf8; / / no resistance of the corresponding bit to pull}Start / / No. A motor, the motor control by timer 1Void, Start_MotorA (){RTCNTB1=Motor_CONT; / / two / / buffer assignment RTCMPB1=Motor_cont;RTCON |= (0x01<<11); / / Auto reload timer 1 RTCON |= (0x01<<9); / / manual refresh set RTCON &= ~ (0x01<<10); / / close reverserRTCON |= (0x01<<8); / / start timer 1RTCON &= ~ (0x01<<9); / / clear manual refresh bit }//A motor stopVoid, Stop_Motor1 (){RTCON &= ~ (0x01<<8); / / clear enable bit timer 1 }/ / change the duty ratio and the steering motorVoid SetPWM (int, valueA, int, drct){RPDATE=drct; / / drct definition PE6 output high level or low level, to control motorRTCMPB1=Motor_COUNT*valueA/0x64; //valueA is the duty cycle can be set to valueA for 0 A to make the motor stop / stop rotation.}Other motor settings are the same as above. The moving speed of the two groups of PWM can be changed at the same time, and the running speed of the car can be adjusted. By setting two different duty cycles, the speed difference between the two wheels is formed, and the purpose of changing the driving direction is achieved.In contrast, 1KHz 100Hz, 10KHz PWM, the output of the driving motor is found when the frequency was 100 Hz, the motor running in clearance rotational state; when the frequency is 10KHz, the motor running instability; when the frequency is 1KHz, the different duty ratio motor operation is very smooth, the speed and the direction of change quickly. Fig. 3 is a modulation waveform produced by an oscilloscope with an PWM frequency of 1KHz, a duty ratio of 30%, and an inversion of the motor.3 conclusionIn this paper, the output frequency of PWM is 1KHZ, and the DC motor is 120 revolutions per minute. The rated voltage is 12V (no additional inductive load outside the motor). The final realization of this subject is the embedded intelligent vehicle system based on ARM, and the PWM speed control of DC motor is one of the important subsystems. The experiment proves that the 16/32 bit RISC processor Samsung of S3C44B0X company is convenient to realize the modulation PWM, programmable, and the motor speed and steering change rapidly without pause, so it can serve the smart car very well.Source: 08, my loveSource of technical data: zhangwrThis article is for learning, reference, use, copyright belongs to the author.Because the content of this website is more and cannot contact the author in time, please contact us according to the method displayed on this website.Design and implementation of DC motor speed regulation system based on ARM0 Introduction in the development of the smart car, an important part is that the smart car can adjust the speed and direction of the vehicle independently according to the surrounding obstacles.

MOSFET output stages substantially reduce the voltage drop and the power dissipation of the outputs of the A3906, compared to typical drivers with bipolar transistors.Output current can be regulated by pulse width modulating (PWM) the inputs. In addition supporting external PWM of the driver, the A3906 limits the peak current by internally PWMing the source driver when the current in the winding exceeds the peak current, which is determined by a sense resistor. A fault output notifies the user that peak current was reached. If internal current limiting is not needed, the sense pin should be shorted to ground.Internal circuit protection includes thermal shutdown with hyster-esis, undervoltage lockout, internal clamp diodes, and crossover current protection.The A3906 is designed for portable applications, providing a power-off low current sleep mode and an operating voltage of 2.5 to 9 V.External PWM Output current regulation can be achieved by pulse width modulating the inputs. Slow decay mode is selected by holding one input high while PWMing the other input. Hold-ing one input low and PWMing the other input results in fast decay. Refer to the Applications Information section for further information.Blanking This function blanks the output of the current sense comparator when the outputs are switched. The comparator output is blanked to prevent false overcurrent detections due to reverse recovery currents of the clamp diodes or to switching transients related to the capacitance of the load. The blank time, t BLANK, is approximately 3 μs.Sleep Mode An active-low control input used to minimize power consumption when the A3906 is not in use. This dis-ables much of the internal circuitry including the output drivers, internal regulator, and charge pump. A logic high allows normal operation. When coming out of sleep mode, wait 1.5 ms before issuing a command, to allow the internal regulator and charge pump to stabilize.Enable When all logic inputs are pulled to logic low, the outputs of the bridges are disabled. The charge pump and internal cir-cuitry continue to run when the outputs are disabled.Charge Pump (CP1, CP2, CP3, and CP4) When supply volt-ages are lower than 3.5 V, the two-stage charge pump triples the input voltage to a maximum of 7 V above the supply. The charge pump is used to create a supply voltage greater than V BB, to drive the source-side DMOS gates. For pumping purposes, a 0.1 μF ceramic capacitor should be connected between CP1 and CP2, and between CP3 and CP4. A 0.1 uF ceramic capacitor is required between VCP and VBB, to act as a reservoir to operate the high-side DMOS devices.Thermal Shutdown The A3906 will disable the outputs if the junction temperature reaches 165°C. When the junction tempera-ture drops 15°C, the outputs will be enabled.Brake Mode When driving DC motors, the A3906 goes into brake mode (turns on both sink drivers) when both of its inputs are high (IN1 and IN2, or IN3 and IN4). There is no protection during braking, so care must be taken to ensure that the peak current during braking does not exceed the absolute maximum current.Internal PWM Current Control Each full-bridge is controlled by a fixed off-time PWM current control circuit that limits the load current to a desired value, I TRIP. Initially, a diagonal pairof source and sink DMOS outputs are enabled and current flows through the motor winding and the current sense resistor, RSx. When the voltage across RSx equals the internal reference volt-age, the current sense comparator resets the PWM latch, which turns off the source driver.The maximum value of current limiting, I TRIP(max) , is set by the selection of the sense resistor, RSx, and is approximated by a transconductance function:I TRIP(max) = 0.2 / R S .It is critical to ensure the maximum rating on SENSEx pins (0.5 V) is not exceeded.Synchronous Rectification When a PWM off-cycle is trig-gered by an internal fixed off-time cycle, load current recirculates in slow decay SR mode. During slow decay, current recirculates through the sink-side FET and the sink-side body diode. The SR feature enables the sink-side FET, effectively shorting out the body diode. The sink driver is not enabled until the source driver is turned off and the crossover delay has expired. This feature helps lower the voltage drop during current recirculation, lower-ing power dissipation in the bridge.Overcurrent Output Flag When the peak current (set by the external resistor) is reached, the fault pin, FLx, is pulled low. When a reset of the PWM latch occurs, the fault timer begins. At each PWM latch reset, the timer is reset to zero. After approxi-mately 300 μs, if no peak current event was triggered, the timer expires and the fault is released. This ensures that during PWM current limiting, the fault pin remains in a fault state.Functional DescriptionApplications InformationVV V V IN1IN2IN3IN4+V BB R –V BB R I OUT1 ,I OUT2I OUT3 ,I OUT4+V BB R –V BB RGND GND+I REG0 A-I REGIN1,IN3IN2,IN4I OUTxV IN(1)V IN(1)External PWM If external PWM is used, the internal current control can either be disabled by shorting the SENSEx pin toground, or it can be used to limit the peak current to a value under the stall current to prevent motor heating. External PWM IN1 control is shown in the upper figure.Stepper Motor Control The A3906 also can be used to control a bipolar stepper motor. The control logic for stepper motor control is shown in the lower figure. The driver is capable of operating in full- and half-step modes.PWM current control in fast and slow decay modesStepper motor control in full- and half-step modesParallel Operation The A3906 can be paralleled for applica-tions that require higher output currents. In paralleled mode the driver can source 2 A continuous. The A3906 has two completely independent bridges with separate overcurrent latches. This allows the device to supply two separate loads, and as a result, when paralleled it is imperative that the internal current control is disabled by shorting the sense pins to ground.Because the overcurrent trip threshold is internally fixed at 0.2 V, the trace resistance must be kept small so the internal current latch is not triggered prematurely. With acceptable margin, the voltage drop across the trace resistance should be under 0.1 V. Ata peak current of 2.5 A, the trace resistance should be kept below40 mΩ to prevent false tripping of the overcurrent latch.Each bridge has some variation in propagation delay. During this time it is possible that one bridge will have to support the full load current for a very short period of time. Propagation delays are characterized and guard banded to protect the driver from damage during these events.Layout The printed circuit board should use a heavy ground-plane. For optimum electrical and thermal performance, theA3906 must be soldered directly onto the board. On the under-side of the A3906 package is an exposed pad, which provides a path for enhanced thermal dissipation. The thermal pad should be soldered directly to an exposed surface on the PCB. Thermal vias are used to transfer heat to other layers of the PCB.Grounding In order to minimize the effects of ground bounce and offset issues, it is important to have a low impedance single-point ground, known as a star ground, located very close to the device. By making the connection between the exposed thermal pad and the ground plane directly under the A3906, that areaDC Motor Operation (Parallel Bridge)IN1/IN3IN2/IN4OUT1A/2A OUT1B/2B Function 00OFF OFF Disabled 10H L FOR01L H REV11L L BRAKEPCB Layoutbecomes an ideal location for a star ground point. A low imped-ance ground will prevent ground bounce during high current operation and ensure that the supply voltage remains stable at the input terminal. The recommended PCB layout shown in the diagram below, illustrates how to create a star ground under the device, to serve both as low impedance ground point and thermal path.The two input capacitors should be placed in parallel, and as close to the device supply pins as possible. The ceramic capaci-tor should be closer to the pins than the bulk capacitor. This is necessary because the ceramic capacitor will be responsible for delivering the high frequency current components.Sense Pins The sense resistors, RS x , should have a very low impedance path to ground, because they must carry a large cur-rent while supporting very accurate voltage measurements by the current sense comparators. Long ground traces will cause additional voltage drops, adversely affecting the ability of the comparators to accurately measure the current in the windings. As shown in the layout below, the SENSE x pins have very short traces to the RS x resistors and very thick, low impedance traces directly to the star ground underneath the device. If possible, there should be no other components on the sense circuits.Note: When selecting a value for the sense resistors, be sure not to exceed the maximum voltage on the SENSE x pins of ±500 mV .ES Package, 20-Contact QFN with Exposed Thermal PadCopyright ©2008-2013, Allegro MicroSystems, LLCAllegro MicroSystems, LLC reserves the right to make, from time to time, such de p ar t ures from the detail spec i f i c a t ions as may be required to permit improvements in the per f or m ance, reliability, or manufacturability of its products.

To reduce potential of electric shock, disconnect all power sources before initiating any maintenance of repairs. Keep hands and foreign objects away from ventilation and other openings. Keep air passages clear.INSTALLATIONAs with all electronic equipment, the enclosure should not be mounted in direct sunlight or exposed to other high level heat radiation from a furnace or other source. If it is necessary to mount the controller near such a heat source, a shield may be used to deflect the heat. It is essential that air movement around the controller be unrestricted and nothing should be left lying on the controller as this would interfere with heat transfer to the air.THE NATIONAL ELECTRIC CODE REQUIRES A SEPARATE FUSED DISCONNECTOR CIRCUIT BREAKER BE INSTALLED IN THE INCOMING AC POWER LINE TOTHE CONTROLLER. (See Controller Rating Table)The table gives AC line voltages, line amperes, DC armature output amps, and maximum field output amps for various motor HP ratings. The AC line amperes (RMS) should be used in sizing the wire forboth the armature output and the AC line input connections. The field current is less than (1) one ampere for each of the motors listed and wire for field connections can be sized accordingly. GROUNDINGIt is imperative that the controller frame be connected to building ground for the safety of the operating personnel.WARNINGAC POWER MUST BE DISCONNECTED FROM THE DRIVE CABINET TO ELIMINATE THE HAZARD OF ELECTRICAL SHOCK BEFORE IT IS SAFE TO TOUCH ANY OF THE INTERNAL PARTS OF THE DRIVE. CIRCUITS MAY BE AT LINE POTENTIAL WHETHER THE ENCLOSED DRIVE IS OPEN OR CLOSED. USE EXTREME CAUTION.The controller has been thoroughly tested at the factory to insure proper operation when installed in accordance with the following installation instructions and diagrams.INSERT - WARNINGThe Model 282 is a non-isolated drive. In other words, the common of the controller (pin 4 of TB1) is connected to the power section. (See Fig.) If the common of the controller is connected to earth ground without an isolation transformer, there will be a direct short circuit from the line to earth ground, resulting in damage to the controller. If the common must be connected to earth ground, an isolation transformer is required. (The secondary of the transformer must not be referenced to earth ground.) Also, the common of one controller should not be connected to the common of other controllers unless each one has an isolation transformer. If isolation is required, Introl can provide an isolation board (part number 241-22CH) to be mounted on the Model 282.SET-UP PROCEDURESELECT MODE OF CONTROLa. Speed - If potentiometer is to control speed, jumper 3 to Pin 9 on TB1 or connect tachometerfeedback to Pin 4 & 9. (Diag. 282)b. Torque - If potentiometer is to control torque, connect jumper from "A" to "D" on the top PCboard and disconnect jumper 3 from 9 on TB1.DETERMINE OPERATING VOLTAGEa. For 115 VAC input and 0-90 VDC output, place jumper on transformer "A" to "D" and "B" to"E".b. For 230 VAC input and 0-180 VDC output, place jumper on transformer "A" to "C" and "B" to"C". Select Current Limit Level.SELECT CURRENT LIMIT LEVELa. Refer to the motor nameplate for DC Armature volts and HP rating. Monitor current limitpotentiometer for maximum 150% F.L. motor current. Full counter-clockwise equalsapproximately 17 amps, and full clockwise equals 3 amps.Install any applicable kits as detailed in kit instructions. Control may now be mounted in itsdesignated area. On chassis mounted units, connect operating devices as shown oninterconnection diagrams at back of manual.CHECK MOTOR AND MOTOR NAMEPLATEa. If motor has a thermal overload, connect as shown on interconnection diagrams at back of thismanual. NOTE - Motor thermal connections are often labeled P1 and P2.b. It the motor has a field winding, connect as shown on interconnect diagrams to control fieldterminals. (With a 115 AC supply, the field output will be fixed at 100 VDC; at 230 VAC thefield output will be 200 VDC.) Some motors have dual fields 150-100 VDC and 100/200 VDC.) Care should be taken to insure the correct voltage is connected.c. If the motor has a permanent magnet field, no field connections need be made. INSTALLATION CHECKSPrior to making the AC input line connections, follow these checks using a volt-ohm-meter. WARNING - Do not use a vacuum tube voltmeter or other similar type of meter that has to be powered with AC power.NOTE - With the red as the positive lead, make the following check:Red + Black - Range of Acceptable ReadingsA2 Al 1-4 OhmsF2 F1 100-700 OhmsFl, F2, Al, A2 GND InfiniteIf any of the checks are not within the indicated range, verify all connections and then recheck.Use of an isolation transformer to reduce the possibilities of ground paths is a recommended safety practice. Pin 4 of TB1 can then be connected to earth ground. (ONLY WITH ISOLATION TRANSFORMER)DISCONNECTING MEANSA fused AC line disconnect or circuit breaker is required by the National Electrical Code (NEC). This AC line disconnect or circuit breaker must be installed ahead of the controller.Transformer ProgrammingFor 115 VAC operation -Jumper A-D, B-EFor 230 VAC operation -Jumper A-C, B-CTorque or Current Mode -When operating in the torque mode the current range from 0 to 100% can be selected by adjustment of the speed/torque pot.OPERATION INSTRUCTIONSMAXIMUM SPEED ADJUSTMENTa.
