Abstract

The invention relates to an electric motor and its slip ring system. The slip ring system comprises an insulating ring and a conductive ring, in which sealing rings are arranged between the connecting surfaces of the insulating and conductive rings. Compared to the conventional sealing method using sealant, the problem of sealant leakage can be avoided by using sealing rings, so that the sealing efficiency of the slip ring system is improved, and the operational stability of the electric motor is also ensured.
