What test should be conducted after the three phase asynchronous motor is made?
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.
