In order to guarantee the quality of maintenance, the three-phase asynchronous motor has the following maintenance project test:

1 winding insulation resistance between the housing and the winding insulation;

2 winding in the test cold state, the determination of the DC resistance;

Determination of 3 rotor winding open circuit voltage (for wound rotor motor and AC motor commutator);

4 no-load test;

5 stall test (only for squirrel cage motor and AC motor commutator);

6 vibration measurement;

7 overspeed test (for cage type cast aluminum rotor motor, only in the form of test);

8 turn - to - turn impulse withstand voltage test;

9 short term elevated voltage tests (e.g., a turn to turn impact withstand voltage test, the test may not be carried out);

10 voltage test.
