YVP系列变频调速三相异步电动机

We have incorporated the advanced technology abroad and CAD technique to design YVP series motor. Therefore at low speed(frequency<50Hz) this motor can ratio 1:10 without torque oscillation, and has a larger starting torque and a smaller starting cuttent and delivers constant output power at high speed. This motor possesses a wide range for speed governing little vibration and low noise, can match with a variety of SPWM converter at home and abroad(as Japanese Fuji. Mitsubishi etc.) to comprise an alternating stepless converter control system. Its power class mounting dimdnsions and center height of bedplate are all according to IEC standards and series Y(ip44)three phase asyn-chronous motor and its interchangeability and versatility are good. The structure of the motor is cage. High reliability and easy maintenance. As cooling fan in built in so under different speeds thd cooling effects is good. 　　 YVP系列电动机吸取了国外先进国家产品这技术，应用CAD设计。低速时（频率＜50HZ）能在1：10范围内作恒转矩调速运行且运行平稳，无转矩脉动现象，并具有较高的起动转矩和较小的起动电流。电动机高速能输出恒功率特性。本系列电动机调速范围宽、振动小、噪声低、能与国内外各种SPWM变频装置（如：日本富士、三菱）相配套，构成交流变频无级调速系统。YVP系列电动机的功率等级与安装尺寸、机座中心高均符合国际IEC标准，其对应关系与Y系列（IP44）三相异步电动机相一致，互换性通用性强。本系统电动机为笼型结构、运行可靠、维修方便，并装有独立的冷却风机、保证电机在不同的转速下、均具有较好的冷却效果。

When compared to other speed governing methods. The speed governing system constituted by series YVP converter control motor and te WPWM converter has remarkable eneroy-saving effects, good speed control performance, wide speed control ratios excellent response; a wide application range. High performance-cost ratio, etc, and is one of the most advanced alternating-current speed governing system. It can be used in the main spindle transmission of NC tool machines. For constant torque and power speed control in the toxtile, chem.istry, metaler Industry etc. and energy-saving speed control for fan and water pumps. Furthermore, it has computer interfaces, and can carry out automatic control of the speed governing system. In general, it is one of high new technical energy-saving products.
