The development of motor winding DC resistance live line test device was introduced. The device adopted choke filter design and realized the isolation of strong and weak electricity. Sample circuits with high precision and high resolution were used, so the DC resistance of motor winding could be measured when it is running. Meanwhile, it can ensure the testing accuracy to meet the standard requirements, improving the efficiency testing precision of the efficient and super efficient motor and it achieves good results in practical application.
