The previous article said that the motor itself has four problems: winding break, winding short circuit, connection error and mechanical failure, and we have already understood the winding break and short circuit of the three-phase asynchronous motor, and today the Senli motor editor will summarize the motor overheating phenomenon caused by wiring errors and mechanical failures.

       A connection error meansThree-phase asynchronous motorThe star connection and triangle connection error, such as the triangle into the star, then the motor is full load operation, the stator winding flow of the current to exceed the rated current, will cause the motor to stop running, if the stop time is longer, but did not cut off the power supply, which will cause the winding serious overheating, and may be burned;

       If the star is connected into a triangle, or a number of coils into a branch of the motor is misconnected into two branches in parallel, will cause the winding and the core overheating, serious will make the motor winding burned. In addition, when the shaft of the three-phase asynchronous motor 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, resulting in overheating.
