FREQUENT MALFUNCTIONS AND SOLUTIONS
1. Stoppage: No-load motor can't start
Possible reasons
1. Circuit broken wires (one of the three is the root)
2. When the child three-phase winding of the a phase breakers ( "Y" type of connection)
3. The power supply voltage and frequency are wrong
Check or calibration methods
1. Check the power supply voltage or individual connection.
2. Check the fuse, feeders of current and each phase of the winding resistance.
3. Check voltage and frequency
2. Stoppage: Motor load in cannot begin at low load or no-load to start when, but in load increase speed that are even stop to plunge
Possible reasons
1. The low-voltage power supply
2. The group turns around the son between short circuit
3. The stator three-phase winding out-of-phase break line ( "A" then method)
4. Overload
Check or calibration methods
1. Check the line voltage;
2. Check each phase winding and each phase no-load current;
3. Check each phase winding resistance;
4. Check the load
