When there is an intersection in the winding of the three-phase asynchronous motor, or there is an intersection on the parallel branch, it will cause the three-phase current imbalance, causing the motor to overheat. When the winding short-circuit fault occurs, the short-circuit current is much larger than the normal working current, which increases the copper loss of the winding, resulting in overheating and even burning of the winding.

       When the triangular connection method is incorrectly connected into a star, the motor is still running with full load, and the current flowing through the stator winding of the three-phase asynchronous motor should exceed the rated current, and even cause the motor to stop running. If the stop time is slightly longer and the power is not cut off, the winding is not only seriously overheated but also may be burned. Coil group into a branch of the motor misconnected into two branches of parallel, will cause winding and core overheating, serious will make the motor winding burned.

       whenThree-phase asynchronous motorWhen the shaft is bent, improperly assembled, and there are problems with the load, the current of the three-phase asynchronous motor will increase, and the copper loss and mechanical friction loss will increase, causing the three-phase asynchronous motor to overheat.
