Definitions

  • Compression spring body consists of a cylindrical coil spring made of spring steel, which can be biased to the lowest possible total length of the system of shutdown and the largest possible wear path of the brush body so far and compressed that their cylindrical turns lie on each other and the spring is biased to block , As a result, the maximum usable wear path of the brush body is determined, which is the ratio of the possible theoretical wear path of the carbon brush to the length of the
