摘要
针对传统测量永磁同步电机反电动势系数需要很多设备与仪器的状况,提出一种测量永磁同步电机反电动势系数的新方法,只需给待测永磁同步电机以单相模式旋转,测量电机的端电压进行合成后,就可以获得电机的反电动势系数。和传统的方法相比,新方法无需采用另一台电机拖动待测电机旋转,也无需精确的速度检测器。实验结果表明:提出的方法与传统测试方法测得的永磁同步电机反电动势系数的大小非常接近。
In view of conditions in which the traditional measurement of permanent magnet synchronous motor back EMF coefficient needs a lot of equipment and instruments, this paper puts forward a method of measuring permanent magnet synchronous motor back EMF coefficient, which measures only permanent magnet synchronous motor with single phase mode rotation. Measuring the motor terminal voltage and synthesis, it may obtain the motor back EMF coefficient. Compared with the traditional test method, the new method drags measurement motor rotation without the use ofother electromotor and an accurate velocity detector. The experimental results show that the permanent magnet synchronous motor back EMF coefficient measured by the proposed method is close to that by the traditional test method.
