The brush lock is due to assembly tightly during assembling three gripper so that it curls after some time in motor and bare motors. The motor happen to have current decreasing and cause rotary too slowly is an important technique problem. At last the motor hasn’t worked due to disconnection. It give company to bring assembly issue for customers. So the motor stall is main issue in motor working. We shall pay more attention to it necessarily and shall be strict quality inspection and we shall monitor the flow line for the sake of decreasing it. We shall solve the problem as soon as possible and communicate with the customer engineers. Unloaded rotation is radical in the base inspection. The engineer need to negotiate with supplying engineers for the qualified material of brush. Increasing inspection into more times is a method to decrease unqualified brushes. Some experiment method is explained to analyze for customer engineers. Two kinds of motors ie. stepping and asynchronous motor and motors used in future in car is explained to further knowledge to motor’s application. Such as the experiment with torque, voice and electric voltage converter. The pseudo soldering results the slow rotary. The reverse voltage is a reason for a motor to slow rotary even stall.
