Multiple reignition makes the frequency and amplitude of overvoltage increase and might do harm to transformer coils by cumulative effects for its surge steepness.
Provided with a kind of winding switching device, the motor runs with the two windings working simultaneously while underloaded, and with the multi circle winding...
Besides the property of the asynchronous motor,the taper asynchronous motor can daff the detent easily,because magnetic force is generated when stator three-phrase windings connect to the electricity.
