An electromotor acceptance shell

The utility model relates to a containing casing of a motor comprising a rear end containing body and a front end cover. The rear end containing body comprises a rear end surface and a containing barrel. The motor is positioned in the containing barrel. One end of the containing barrel which is far away from the rear end cover extends outward to form a joint surface, and the joint surface is equipped with a plurality of positioning holes. The front end surface is equipped with a positioning protuberance which is matched with the positioning hole for positioning. The containing casing of the motor of the utility model has the advantages of the simple structure and the simple fabrication technology. The positioning protuberance and a central bearing chamber can be punched integrally to fabricate, thereby ensuring the concentricity of the positioning protuberance and the central bearing chamber.
