Three-phase asynchronous motor open phase fault operation

1,the lack of the phenomenon of phase operation Three-phase asynchronous motor 220v ac electric motors open phase running "refers to a three phase power supply phase lack a phase or three phase winding of the motor circuit there is a phase in the motor caused by abnormal running state also called open phase running. Destroyed most of the three-phase asynchronous motor winding is caused by motor open phase running,when the motor is in a state of overload,under the same load power,lack of phase running current rotor and stator is higher than normal operation of the current times.At this point,if not handled in time,motor winding will be burned.If the motor before starting circuit,a phase may only after turning on the power single phase capacitor start induction motorsupply noise is not www.facebook.com/guohong.trading

starting,must cut off the power immediately,otherwise,will burn winding.
