Abstract

The invention provides a motor case, and the motor case comprises a first cylinder and a second cylinder which is concentrically disposed in the first cylinder. The second cylinder is provided with a carbon brush holder installation part. The motor case defines an axial direction extending along a central axis, and a radial direction extending in a direction perpendicular to the axial direction. One end of the second cylinder is recessed into the first cylinder from one corresponding end of the first cylinder in the axial direction, thereby forming a stepped part. The carbon brush holder installation part is deflected inwards in the radial direction of the central axis from one end of the second cylinder. The invention also provides a motor comprising the motor case.

Description

technical field [0001] The invention relates to a motor housing and an electric motor comprising such a motor housing. Background technique [0002] A motor generally includes a motor housing and various components accommodated in the motor housing, including but not limited to magnetic pole pieces, field windings, armatures, commutators, carbon brushes, motor output shafts and other functional components, as well as accessories such as bearings. [0003] In the prior art, the motor casing is generally machined from a casting. For example, in order to fix the carbon brush holder for installing the carbon brushes, the inner surface of the motor housing is usually processed, so that a stepped portion is formed on the inner surface of the motor housing for fixing the carbon brush holder. [0004] Machining the inner surface of the motor housing not only wastes material but also complicates the manufacturing process of the motor housing. [0005] It is hoped that the structure...
