This paper presents two methods for measuring the no-load back electromotive force of permanent magnet synchronous motor specified in GB/T 22669-2008.At the same time,according to the relevant provisions in GB/T 25123.4-2015,a more convenient deceleration method is proposed,and the accuracy of the method is verified.Taking the high-speed permanent magnet motor with air bearing and the permanent magnet synchronous linear motor as examples,which are more complicated in the measurement of no-load back electromotive force,combined with the measurement principle of related methods,the measurement process of no-load back electromotive force is introduced in detail.
