SM Series Servo Motors Brushless servo motors featuring high performance slotless designThis design eliminates all detent torque in the motor, allowing the SM Series motors to provide extremely smooth motion, especially at low speeds. The slotless design also creates a higher rotor inertia, which is ideal for applications involving high inertial loads (such as lead screws and belt drives).Features• NEMA size 16 and 23• 0.8 to 11.3 lb-in continuous torque• Brushless construction • Slotless design providesnegligible detent torque, reduced torque ripple and high inertia • High-performance neodymium magnets• Thermostat protected • TENV housing • IP65 option• Feedback options – Encoder/Hall effect – Resolver• Connectorization choices • Special winding availability• Custom modifications available • Two-year warranty • CAD models available •CE CompliantContact Information:Parker Hannifin CorporationHydraulic Pump and Power Systems Div.14249 Industrial Pkwy.

The PS option joins the motor phase wires and brake leadsIP65.NOTE: For customers preferring to build their own mating cables, a PS connector kit (Part #: PS-CONN-KIT), is available. The kit contains a mating PS power connector, PS feedback connector and connector pins, allowing customers to build cables to their own specification. Special tools are not included in the kit.NOTE: Brake will operate regardless of polarity of connectionLC – Low Cost (-xLCx) Pin ConnectionsLC Incremental Encoder/Hall (R) PinLC Resolver (R) Pin ConnectionsThe LC connector option for the SM motors features a high-quality and low cost molded connector. This option uses the very common Amp, or Tyco brand of connectors on the ends of 8” motor and feedback cables. These connectors are usually available from most electrical supply houses.Feedback2Power PowerBrakeThe LC connector option is available on all SM size 16 and 23 stack length motors. The feedback type selections that are available with the LC option are J (incremental encoder) and R (resolver) feedback options.The LC connections support the brake option for SM motors. When the brake option is ordered, the motor ships with three individual connectors: One for feedback, one for power and the last for the brake. Without a brake, the motor only comes with the feedback and power connectors.Feedback Connector Tyco 172171-1Mating Connector Tyco 172163-1Mating Pin (F) Connector Tyco 170362-1Tyco 172167-1Tyco 172159-1Tyco 170362-1 Tyco 170362-1Wiring Connections for:FL – Flying Leads with Enclosed Feedback (-xFLx) FO – Flying Leads with Exposed Feedback (-xFOx)FL and FO Cable MotorPower, Motor Feedback andFO/FL Flying LeadsThe FO/FL cable option for the SM motors features flying leads for both feedback and power connections. The only variable is whether or not the feedback device is fully enclosed (FL) or fully exposed (FO).These options are for OEM customers that wish to reduce cost as much as possible and fully integrate their own cable solutions.10 - 10’ hard wired cableThe “10” cable option for the SMhard wired into the rear of the motor. The cables have full strain relief and completely enclosed feedback. While custom lengths are available, it is not recommended to exceed 10 feet between motor and drive.NOTE: Brake will operate regardless of polarity of connection10’ Cable Motor Power, Motor Feedback and Brake (J) Wiring ConnectionsMS – Military Style (-xMSx) Pin ConnectionsMS Incremental Encoder/Hall and Brake (E and L) Pin ConnectionsMS Power Pin ConnectionsAmphenol CONN PT06E-14-12P(023) Feedback connector part number:Amphenol CONN PT02E-14-18S(023)MS Resolver and Brake (R) Pin ConnectionsPowerFeedbackThe “MS” connection option for the SM Series motors provides quick disconnect, bayonet style connectors attached to the motor body. Mating cables are specified and ordered separately.With the “MS” connection option, the motor phase wires are in one connector, and the hall, encoder, temperature switch, and brake wires are in the other connector. This option works well when using an amplifier with a built-in controller, or when all cables enter into a cabinet or enclosure and then are wired into a terminal strip.When specifying the “R” (resolver) feedback option, the motor phase wires reside in one connector, the resolver signal, temperature switch, and brake wires in the other.The “GS” connection option for the SM Series motors provides quickdisconnect, bayonet style connectors attached to the motor body. Mating cables are specified and ordered separately. Wiring for the “GS”connection option for SM motors is similar to the “MS” option, except thetemperature switch leads have been moved to the feedback connector. This connection option should be selected when operating the SM motors with the Gemini family of amplifiers.GS – Gemini Amp Series Connection (-xGSx)GS Motor Wiring ConnectionsGS Encoder/Hall Feedback Wiring ConnectionsPowerFeedbackFeedback OptionsResolver SpecificationsHall-Effect SpecificationsEncoder SpecificationsR2R1S3S1S1-S3 R1-R2E S2-S4 = KE R1-R2 SINØPhase B-APhase A-CClockwise rotation as viewed from front shaft.Phase C-BHall #1Hall #2Hall #3Resolver SchematicCommutation ChartSM Series OptionsFill in an order code from each of the numbered fields to create a complete model order code.SeriesSMBrushless Servo MotorsFrame (Magnet Length)161Size 16 frame, 1 stack magnet 162Size 16 frame, 2 stack magnet 231Size 23 frame, 1 stack magnet 232Size 23 frame, 2 stack magnet 233Size 23 frame, 3 stack magnetWindingA 16 or 23B16 or 23FeedbackE 1000 ppr encoder*L 5000 line encoder*RResolver***Includes Hall-effect**Not available on any size 16 FrameShaft OptionsN Normal F FlatKKeyway**Not available on size 16 motorsConnectionPS Parker standard connectors, all feedback optionsLCLow cost connectors 1010 ft.

上海电器 TM、TMW系列矿山磨机用同步电动机 说明书

一、概述TM、TMW系列同步电动机是与矿山磨机配套的专有系列产品。
近年来随着空气离合器的广泛应用,磨机得到快速发展,与之配套的TDMK *系列球磨机用同步电动机产品,无论规格、容量、型式、性能均得到提升和完善。
二、型号说明三、性能特点本系列产品结构合理、具有效率高、失步转矩大、振动小、安装维护方便等显著特点。
传统齿轮联轴结构的电动机具有较大的堵转转矩,能直接启动带一定负载的磨机,但同时亦因堵转电流较大而对电驱设备提出的要求较高。
采用空气离合器联轴结构的电动机轴中心打有深孔,尾端带压缩空气接口法兰。
电动机空载启动,堵转电流小而对电驱设备要求不高。
本系列产品冷却方法为IC01,外壳防护等级为IP20或IP21。
四、主要技术数据 Main Technical Data1. General introductionTM, TMW series synchronous motor is developed especially for drivingcoal mill.Going with the wide application of air clutch, coal mill is developing quickly which also improve the specification, output, type and performance of the old TDMK series ball mil synchronous motor.2. Type designation3. Performance characteristicThe series motor is with rational structure, high efficiency, large pull-out torque, low vibration, and convenient for installation and maintenance, etc.The motor adopting traditional gear coupling structure has large locked- rotor torque and could start on-load mill directly, but simultaneously, elec-trical drives equipment has to achieve much higher requirement owing to large locked-rotor current.The motor adopting air clutch coupling structure is drilled deep hole in the shaft center and with compressed air connecting flange in the end. Motor no-load starting and low locked-rotor current could decrease the requirement for electrical drives equipment.The cooling method of this series motor is IC01 and the enclosure protection class is IP20 or IP21.*TDMK (被替代的老型号)the replaced motor type注:随着技术的进步和有关国内外标准的修改,样本内尺寸及技术参数改动时,恕不另行通知。
