Abstract
The utility model discloses a motor rear cover, which is used for installing a rotor. The motor rear cover comprises a round metal sheet, ceramic chips, ceramic sleeve pipes and nuts. The axial end face on one side of the round metal sheet is provided with at least one threaded pole. The ceramic chips are sleeved on the threaded poles and further contact the axial end face of the round metal sheet. The ceramic sleeve pipes are sleeved on the threaded poles and contact the ceramic chips. The nuts and the threaded poles are connected so as to fix the ceramic chips and the ceramic sleeve pipes. The anti-corrosive performance, the heat resistance and the oxidation resistant performance of the motor rear cover are improved. The overall service lifetime of the motor rear cover is thus prolonged.
