35- Rear end cover

The end cover is a back cover installed behind the motor and other housing, commonly known as "end cover".

The end cover is good or bad, which directly affects the quality of the motor. Therefore, we must first understand what is called a good or bad standard of an end cap. A good end cover, mainly from its heart - brush blade, its role is to drive the rotation of the rotor, this part is the key part, it mainly has the following standards: 1, not high. 2. Not low. 3. Not short. 4. No fork. 5. Don't bend. 6. Not bending.

Because as long as there is a link of the brush, it will affect the quality of the motor. Brush too high, will touch the varistor; Too low and you'll hit a white washer; (seen in rotor) too short for it to touch the rotor. This would disable the rotor; Brush bifurcation, will make the current unstable; Of course, it can not bend, it will make the current abnormal. It should be added that the brush blade of the end cap is very crisp and tender, and a little carelessness will cause the brush to fork, bend and so on.
