摘要
对目前主流的三相异步电机效率测定方法进行了比较和研究。由于不同的效率测定方法试验项目不尽相同,设计并实现了一个效率测试系统满足不同测定方法和型式试验的要求,详细介绍了该系统的组成和实现。以NEMA电机为例,分别采用不同测定方法确定效率,比较了试验结果。目前,该系统在南车株洲电机有限公司技术中心已投入使用。
The major methods of efficiency testing for three-phase asynchronous motor were compared and re- searched. The test items are different for efficiency testing methods. A efficiency testing system was designed and re- alized, which was satisfied for different efficiency testing methods and type testing. The composition and realization of the system was introduced in detail. Take the case of NEMA motor, the motor efficiency was calculated by different methods and the results were compared. Now, the system was put in commission in technology center of CSR Zhuzhou Electric Co. , Ltd.
