磁滞联轴器的工作原理
磁滞联轴器的工作原理
磁滞联轴器是一种常用的传动装置，在机械传动系统中起到很重要的作用。
它的工作原理是基于磁滞现象，利用磁场的力量来传递动力。
磁滞联轴器是由两个磁性材料组成的，它们之间通过一层隔离层隔开。
当磁场作用于磁性材料时，会形成一个磁通量，从而在磁性材料中产生涡流，这会导致磁性材料本身发生热量和能量的损耗。
这种磁通量的大小和方向可通过改变磁场的大小和方向来控制。
当磁滞联轴器的两个磁性材料处于不同的磁场中时，它们会产生一个磁滞现象。
这种磁滞现象会阻碍磁性材料的运动，从而产生一定的阻力。
当磁场强度增加时，阻力也会随之增加；当磁场强度减小时，阻力也会随之减小。
这种阻力的大小也可以通过调整磁场的大小和方向来控制。
通过在磁滞联轴器上安装驱动和被驱动轴，可以将动力传递到被驱动轴上。
在传动过程中，磁滞联轴器会起到一个转速和扭矩的调节作用，从而保证传动系统的正常工作。
在某些特殊的应用中，磁滞联轴器还可以用于保护传动系统，当系统出现异常负载时，磁滞联轴器会自动断开，从而避免系统损坏。

Magtrol HD系列磁滞动力计说明书
HD SERIES HD SERIESHYSTERESIS DYNAMOMETERSMAGTROL offers 3 types of dynamometer brakes to absorb load: Hysteresis (HD Series), Eddy-Current (WB Series) and Magnetic Powder (PB Series). Each type of Dynamometer has advantages and limitations and choosing the correct one will depend largely on the type of testing to be performed. With over 50 standard models to choose from, Magtrol Sales professionals are readily available to assist in selecting the proper Dynamometer to meet your testing needs.FEATURES▪16 Standard Models with Maximum Torque from2.5 oz·in to 500 lb·in (18 mN·m to 56.5 N·m)▪14 High Speed Models Available▪Hysteresis Braking System: provides precise torqueloading independent of shaft speed▪Motor Testing: from no load to locked rotor▪Standard Torque Units: SI(English & Metric available upon request)▪Accuracy: ± 0.25 % (full scale)▪Air Flow Sensor: For protection against overheatingand operator error▪Base Plates: available in long or short versions▪Custom Dynamometers: for special torque andspeed requirements▪Easy CalibrationDESCRIPTIONHysteresis Brake Dynamometers (HD Series) are versatile and ideal for testing in the low to medium power range (maximum 14 kW intermittent duty). With a Hysteresis Braking system, the Dynamometers do not require speed to create torque, and there-fore can provide a full motor ramp from free-run to locked rotor. Brake cooling is provided by convection (no external source), by compressed air or by dedicated blower, depending on the model. All Magtrol Hysteresis Dynamometers have accuracy ratings of ± 0.25 % (full scale) depending on size and system configuration. To better integrate dynamometers into systems, Magtrol offers both long and short base plates. The shorter base plate facili-tates easier motor mounting when used with T-slot tables and Magtrol Adjustable Motor Fixtures, where as the long base plates are better suited for table top testing.APPLICATIONSMagtrol motor test systems can be found in test labs, at inspec-tion stations, and on the manufacturing floors of most of the world’s leading manufacturers, users and certifiers of small to medium sized electric, pneumatic and hydraulic motors, as well as internal combustion engines. Magtrol supplies motor test systems for a wide array of industries including: Appliance, Auto-motive, Aviation, Computer, HVAC, Lawn and Garden, Medical and Dental, Electric Motor, Office Equipment and Power Tools.Fig. 1: HD-715 | Hysteresis DynamometerMagtrol’s Hysteresis Dynamometers cover a wide range of Torque, Speed and Mechanical Power ratings. To select the appropriate size Dynamometer for your motor testing needs, you will need to determine the Maximum Torque, Speed and Power applied to the Dynamometer.MAXIMUM TORQUEThe Magtrol Hysteresis Absorption Dynamometer will develop braking torque at any speed point, including low speed and stall conditions ("0" rpm). It is important to consider all torque points that are to be tested, not only rated torque, but also locked rotor and breakdown torque. Dynamometer selection should initially be based on the maximum torque requirement, subject to determining the maximum power requirements. MAXIMUM SPEEDThis rating is to be considered independent of torque and power requirements, and is the maximum speed at which the Dynamometer can be safely run under free-run or lightly loaded conditions. It is not to be considered as the maximum speed at which full braking torque can be applied.MAXIMUM POWER RATINGSThese ratings represent the maximum capability of the Dyna-mometer Braking System to absorb and dissipate heat gener-ated when applying a braking load to the motor under test. The power absorbed and the heat generated by the Dynamometer is a function of the Torque (T) applied to the motor under test, and the resulting Speed (n) of the motor. This is expressed in these Power (P) formulas:The Dynamometer’s ability to dissipate heat is a function of how long a load will be applied. For this reason, the maximum power ratings given are based on continuous operation under load, as well as a maximum of 5 minutes under load.To safely dissipate heat and avoid Dynamometer failure, the maximum power rating is the most important consideration in selecting a Dynamometer.Magtrol Hysteresis Dynamometers absorb power with a unique Hysteresis Braking Systemwhich provides frictionless torque loading independent of shaft speed. The HysteresisBrake provides torque by the use of two basic components - a reticulated pole structureand a specialty steel rotor/shaft assembly - fitted together but not in physical contact.Until the pole structure is energized, the drag cup can spin freely on its shaft bear-ings. When a magnetizing force from the field coil is applied to the pole structure,the air gap becomes a flux field and the rotor is magnetically restrained, providinga braking action between the pole structure and rotor.Magtrol’s M-TEST Software isa state-of-the-art motor testingprogram for Windows®-baseddata acquisition. Used with aMagtrol DSP 7010 Dynamom-eter Controller, Magtrol M-TESTSoftware provides the control ofany Magtrol Dynamometer and runs test sequences in a manner best suited to the overall accuracy and efficiency of the Magtrol Motor T est System. The data that is generated by Magtrol’s Motor T esting Software can be stored, dis-played and printed in tabular or graphic formats, and can be easily imported into a spreadsheet.Written in LabVIEW™, M-TEST has the flexibility to test a majority of motor types in a variety of ways. Because of LabVIEW’s versatility, obtaining data from other sources (e.g. thermocouples), controlling motor power and providing audio/visual indicators is relatively easy. Magtrol’s M-TEST Software is ideal for simulating loads, cycling the unit under test and motor ramping. Because it is easy to gather data and duplicate tests, the software is ideal for use in engineering labs. T ests can be programmed to run on their own and saved for future use allowing for valuable time savings in production testing and incoming/outgoing inspection.SI: P[W] = T[N·m] × n[min-1]× (1.047 x 10-1) English: P[W] = T[lb·in] × n[rpm]× (1.183 x 10-2) Metric: P[W] = T[kg·cm] × n[rpm]× (1.027 x 10-2) All of Magtrol’s controllers, readouts and software calculate horsepower as defined by 1 [hp] = 550 [lb·ft /s].Using this definition:P[hp] = P[W] / 745.7Pole StructureBearingAir GapOPEN LOOP SYSTEMSMagtrol offers both open loop manual test systems and PC-based closed loop test systems. A typical open loop system will consist of a Dynamometer and a Magtrol DSP 7010 Dynamom-eter Controller in Open-Loop configuration. A Magtrol Single or Three-Phase Power Analyzer, which allows for the capturing of volts, amps, watts and power factor, can be included as an option. An open loop system is often used for quick pass / fail testing on the production line or at incoming inspection. Magtrol’s DSP 7010 Dynamometer Controller provides pass / fail testing as a standard feature.CLOSED LOOP SYSTEMSIn a closed loop motor test system, data is collected on a PC using Magtrol’s M-TEST Software, DSP 7010 Dynamometer Controller, and requisite interface cards and cables. Magtrol’s DSP 7010 Dynamometer Controllers compute and display mechanical power (in horsepower or watts) in addition to torque and speed. A Single or Three Phase Power Analyzer, a required component in a test system measuring motor efficiency, can be integrated into this system as well as Magtrol’s Temperature Testing Hardware.MODEL 7500Computer witha) All -5C dynamometers are 5 Volt Output.Please, contact our sales representative for 6C (English units), 7C (Metric units) or 8C (SI units) specifications.b) Operating at the continuous power rating for periods of up to 4 hours isacceptable. However, operating for extended periods at high temperatures will result in premature component and bearing failure. Limiting the length of the cycle and the component temperatures will guard against premature failure. Where continuous duty is desired for longer time intervals, compo-nent temperatures should be maintained less than 100°C; monitoring the outside brake surface temperature is a sufficient reference.c) Requires air cooling provided by user. Regulator and filter package isprovided as standard d) Blower is includede) The maximum speed will depend on what type of keyway (if any) is usedon the shaft. Unless specified, the dynamometer shaft will be made withouta keyway.ELECTRICAL POWERHD-100 / 400 / 500 SERIES WITH LONG BASE PLATEb) Shaft Flats are not available on high speed models.a) These dimensions represent the distance between mounting holes.

磁性联轴器
磁性联轴器折叠编辑本段发展联轴器广泛应用在各种通用机械上，用来联接两根轴使其一同旋转，以传递扭矩和运动。
传统的联轴器都必须通过主动轴与从动轴的相互联结来传递扭矩，其结构复杂，制造精度高，超载时容易导致部件的破坏。
特别是主动轴与从动轴工作在需要相互隔离的两种不同介质中时，必须使用密封元件进行动密封，这样就存在要么加大旋转阻力来保证密封可靠，要么密封不严产生泄漏的问题。
另外，随着密封元件的磨损、老化，会加剧泄漏，尤其是在有害气体(有害液体)存在的系统中，一旦泄漏就会污染环境，危及生命。
传统联轴器皆为接触式联轴器,根据其内部是否具有弹性零件,可分为弹性联轴器和刚性联轴器。
弹性联轴器内部具有金属弹簧或橡胶塑料等制成的弹性零件,所以具有缓冲吸振的功能和适应轴线偏移的能力。
它适用于承受变载荷冲击以及起动频繁和有正反转的场合,也适用于2轴线不能严格对中的场合。
刚性联轴器中没有弹性零件,所以没有缓冲吸振的能力。
磁力传动联轴器属非接触式联轴器,它一般由内外2个磁体组成,中间由隔离罩将2个磁体分开,内磁体与被传动件相连,外磁体与动力件相连。
磁力传动联轴器除了具有弹性联轴器缓冲吸振的功能外,其最大的特点在于它打破传统联轴器的结构形式，采用全新的磁耦合原理，实现主动轴与从动轴之间不通过直接接触便能进行力与力矩的传递，并可将动密封化为静密封，实现零泄漏。
因此它广泛应用于对泄漏有特殊要求的场合。
折叠编辑本段原理磁力传动联轴器主要有2种结构:平面磁力传动联轴器和同轴磁力传动联轴器。
磁体以轴向充磁,耦合磁极成轴向配置的叫平面磁力传动联轴器。
磁体以径向充磁,耦合磁极成径向配置的叫同轴磁力传动联轴器。
现以同轴磁力传动联轴器为例,来说明其工作原理。
磁力传动联轴器由外磁体、内磁体和隔离罩组成。
内、外磁体均由沿径向磁化且充磁方向相反的永磁体组成,永磁体以不同极性沿圆周方向交替排列,并固定在低碳钢钢圈上,形成磁断路连体。
隔离罩采用非铁素体(因而是非磁性)的高电阻材料制造,一般用奥氏体不锈钢。

核心部件主要由一个永磁盘和一个感应盘组成，二者相对布置并调有一定的间隙。
永磁盘上分布着数块极性交替变化的磁钢，从而在感应盘上形成了一个复杂的极性交替变化的磁场。
当永磁盘与感应盘之间有相对转动时，感应盘磁场的变化总是滞后于永磁盘磁场的变化，从而产生一个磁滞力矩以阻止它们之间的相对转动，即实现了“磁联接”，当磁滞力矩不足以阻止它们之间的相对转动时，则永磁盘与感应盘产生滑差。
磁滞联轴器所传递的转矩即永磁盘与感应盘间的磁滞力矩，磁盘间隙一定时该力矩是恒定值，因此，磁滞联轴器具有输出转矩恒定和过载时打滑的特点。
通过调节磁滞联轴器的永磁盘和感应盘的间隙，磁滞联轴器的传递扭矩可以在一定的范围内变化。

意事项
1. 磁滞联轴器的工作原理
磁滞联轴器的工作原理是在一个由数块永久磁铁组成的磁盘的对面放置一个由强磁材料制成的感应盘中间留有空气隙磁盘上有一个多极交替的磁场当两个盘之间出现转速差时磁盘将交替磁化对面的感应盘产生一个抗拒滑差的扭矩实现了两盘之间的磁联接
从而达到了既能传递一个基本恒定的扭矩又能允许滑差的目的ZPMC的磁滞联轴器可根据需要装置一个超越离合器当输出端反转时磁滞联轴器可起到能耗制动的作用当输入端停转时磁滞联轴器能始终在一个旋转方向保持恒定的制动力矩
2. 磁滞联轴器力矩的测量与调整
