[0002] The insulating protective shell is an important component used to protect the motor stator. It mainly consists of a stator sleeve, upper and lower end covers and an empty slot. The shape matches the contact part of the stator body. This insulating protective shell is manufactured through open mold injection molding technology, which can cooperate more closely with the motor stator body, so that the surface and inner diameter of the stator are fully covered, playing a more complete protective role.
