Quoted at the problem of bad contact between the brushes and slip rings of wound rotor motor of YZR range,this paper introduces a very efficient device for detecting the radian of the brush holder designed according to actual requirement.

Based on practice,the reasons of large and medium-sized high voltage wound rotor three-phase asynchronous motor rotor failure were expounded,and viable approach was designed.
