When the motor winding current is too large, the higher current density will cause the winding resistance to increase and cause serious heat generation. The heat generated by the motor will be dissipated through the insulation. When the heat reaches a certain level, the structure of the insulating material will undergo qualitative changes, such as the motor The performance requirements of different insulation grades such as B, F, and H involved in the table correspond to the maximum working temperature that the insulating abuiya jurewa.
