However, the above patent also has the following disadvantages: (1) Silver films and carbon films are printed on the driving plate, so that the method is not suitable for industrial mass production, and the reject ratio of products is high; (2) The gap between the sliding block and the bracket is large, and the silver film and the carbon film easily enter foreign matters, so that the brush and the silver film/carbon film are in poor contact and even damaged. (3) The brush is in direct contact with the silver film/carbon film, and the film coating is easy to damage after a long time, so that the precision is greatly reduced or the steering engine cannot be used at a certain point. (4) The electric brush belongs to a vulnerable part, and is easy to rebound due to overlarge stress. The production process is complicated and the cost is increased.
