Motor Fault and way to solve
Lack of phase operation
In daily work, lack of phase operation is one of the common faults. As long as one phase of the three-phase power supply is open, it will cause the motor to operate under phase loss. The lack of phase operation may be caused by the fusing of the fuse on the line, the poor contact of the switch contacts or the wire joints, etc. If a three-phase motor is in a stopped state after missing one phase of power, it will stall (cannot start) because the combined torque is zero. The locked-rotor current of the motor is much larger than the normal working current. Therefore, in this case, too long a power-on time or frequent power-on starting will cause the motor to burn out. When the running motor lacks one phase, if the load torque is small, it can still keep running, only the speed drops slightly, and abnormal noises are made. When the load is heavy, the motor winding will be burnt if the running time is too long.
