The end cover is a back cover installed at the back of the motor  other casings, commonly known as the "end cover". There are many types of end caps. Is suitable for toy motor end cover. It is mainly composed of cover body, bearing  brush piece. Whether the end cover is good  bad directly affects the quality of the motor. So, let's first understand what is the standard for the quality of an end cover. A good end cover mainly comes  its heart - brush blade. Its function is to drive the rotor to rotate. This part is a relatively key part. How can we measure it? It mainly has the following standards:  high,  low,  short,  fork,  bend,  bend.

The end cover generally refers to the cover at both ends of the motor whose axial dimension is larger than the radial dimension. Its main function is to determine the spatial position of the rotor shaft. Of course, it needs to cooperate with different forms of bearings. It is connected to the shell of the fixed motor stator through the end cover to ensure the clearance between the rotor  the stator. Generally, it is cast iron technology. Small motors can also be sheet metal stamping.

Because as long as there is a link for business trip, the quality of the motor will be affected. If the brush is too high, it will touch the varistor; if it is too low, it will touch the white washer; if it is too short, it will  touch the rotor. This will make the rotor unable to operate; the brush bifurcates, which will make the current unstable; of course, it can  bend, which will make the current abnormal. It needs to be added that the brush piece on the end cover is very crispy  tender. A little carelessness will make the brush bifurcate  bend.
