1 Gerenal DescriptionSeries YR, YRKS & YRKK high-voltage wound-rotor three-phase induction motors (frame size 355~630) are the newest products, being of the 1990’s advanced technique levels, developed and famufctured by our company.These series motors can be used to drive various commonly used machines, such as compressors, water pumps, crushers, cutting lathes, conveyors, air-blowers, coal-grinders, rolling mills, and belt conveyers etc.With the material chosen exquisitely and the products excellent workmanship, these series motors are engineered with many remakble features, such as high torque index, low noise, small vibration, high reliability, easy operation, mounting and maintenance etc.For these series motor, the output rating, mounting dimensi ons and electric properties conform to China Industry Standard JB/T7594 Series YR High-Voltage Wound-Rotor Three-Phase Induction Motors Specfications, and specifications specified in other relative standards and IEC Standard 72—2.For these series motors, the cooling rorm is IC01, IC81W and IC611 according to China National Standard GB1993 and IEC Standard 34—6 Cooling Form of Motors, and the mouting arrangement is horizental foot-mounted (IMB3), conforming to GB997 and IEC34—7 Code of Motor Construction and Mounting Arrangement. For the other requirements, consult with our company further.本系列电动机按防护等级和冷却方式可分为以下三个系列：These series motors can be divided into three series types according to protection type and protection degree.2型号意义2 Type DesignationThe explanation of type designation of motors is as follows:3结构说明该系列电动机采用国际流行的箱式结构，机座为钢板焊接而成，重量轻、钢度好。
定、转子绕组均采用F级绝缘结构，端部有可靠的固定和绑扎，并经真空压力浸渍溶济漆工艺（VPI）处理。
因此，电动机具有优良的绝缘性能，机械强度好，防潮能力强。
该系列电动机所用的轴承有滚动轴承和滑动轴承两种型式，依据电动机功率大小和转速而定，其基本型式的防护等级为IP23和IP44，接线盒的防护等级为IP54，位于电动机的右侧（从轴伸端视之）。
基本设计电动机的集电环位于轴承外侧，防护等级为IP23.如果用户需要其它型式的防护等级，或集电环位于轴承的内侧，须在订货时特殊要求。
4使用条件4.1海拔不超过1000m。

4.5电源电压6000V，频率50Hz。
3 Constructional FeaturesThese series motors adopt international fashionable box construction. Frames are welded with sheet steel, being of the merits of lightweight and well rigidity. Both stator and rotor wingdings are Class F insulation. On the ends of them, the fixing and binding measures are supplied reliably. They are steated with vacuum-pressureimpregnate solvenless varnish processe (VPI). These processes enable the motors to possess excellent insulation property, high mechanical strength, and high moisture-resistant ability.In accordance with the motor output and speed, two kinds of bearings can be equipped, one is rolling bearings and the other is friction bearings. The protection degree is IP23 and IP44 for the basic types and IP54 for the terminal boxes. The terminal box is generally located on the right side of the motors (viewing from DE).For the basic designed type motors, the collecting electric rings are generally located at the outside of the bearings with the protection degree IP23.For other protection degree or the collecting electric rings locating at the inside of the bearings, please state specially when ordering.4 Service Conditions4.1 The altitude is up to 1000m.4.2 The highest ambient temperature does not exceed 40℃.4.3 The lowest ambient temperature is -15℃ for the motors with rolling bearings and +5℃ for the motors with friction bearings.4.4 The average highest relative humity in the most humid month is 90% and meanwhile the average lowest temperature of this month does not exceed 25℃.4.5 The supply voltage is 6000V and the frequency 50Hz.5主要技术数据5 Min Technical Data5.1 YR、YRKS系列绕线转子三相异步电动机技术数据（6000V）。
