5.5kW永磁调速同步电动机的设计与分析

Design and Analysis of 5.5 kW Speed-adjustment Permanent Magnet Synchronous Motor

永磁同步电动机气隙磁场是由永磁体提供的,无需励磁电流,采用闭环矢量控制策略有效地提高了永磁同步电动机变频调速的动态性能,本文介绍5.5 kW稀土永磁调速同步电动机的设计和样机测试,分析调速性能和经济指标。

Permanent magnet synchronous motor air-gap magnetic field was provided by permanent magnets,without excitation current.The dynamic performance of permanent magnet synchronous motor speed adjustment through varying frequency was improved by closed-loop Vector control stratagem.5.5 kW speed-adjustment rare earth Permanent magnet synchronous motor（REPMSM） design and prototype motor test were introduced,speed-adjustment performance and economic indicators were analyzed.
