Abstract

The motor end cover comprises an end cover shell (10), a bearing hole is formed in the end cover shell (10), a mounting groove (11) is formed in the side wall of the first end of the bearing hole, the mounting groove (11) is used for mounting a sensor, a bush (20) is arranged at the second end of the bearing hole, and the bush (20) is used for mounting a bearing. By adopting the technical scheme of the invention, the problem of low motor control precision caused by unreasonable structural arrangement of the motor end cover in the prior art is effectively solved.

Description

technical field [0001] The present invention relates to the technical field of motor equipment, and in particular, to a motor end cover and a motor having the same. Background technique [0002] The bearing bushing of the existing motor end cover is mostly fixed on the motor end cover by bolts, and the assembly of the bearing bushing is complicated; at the same time, the bearing bushing and the position sensor installation grooves are distributed on both sides of the motor end cover, which is difficult to improve during machining. The coaxiality of the axis of the bearing bushing and the axis after the position sensor is assembled affects the precision of the resolver control of the motor assembly, which in turn affects the precise control of the motor. [0003] The structural design of the motor end cover in the prior art is unreasonable, which usually leads to unreasonable utilization of the space at the end of the stator inside the motor, thereby making the axial dimensio...
