Problems solved by technology

[0002] In the motor industry, the motor end cover is usually formed by stretching the sheet material. Although the motor end cover formed by stretching the sheet material has the advantages of fast and efficient production, the stator and rotor are prone to appear after the motor is assembled. The lack of coaxial precision between the stator and rotor causes the unevenness of the air gap between the stator and the rotor to become larger, resulting in greater electromagnetic noise from the motor
When the coaxial precision is seriously insufficient, there may even be direct friction between the stator and the rotor, resulting in the failure of the motor and greatly reducing the reliability

Abstract

The invention discloses a motor end cover assembly and a motor. The motor end cover assembly comprises a motor end cover (1) and a bearing seat (2) which are independent mutually, wherein the end surface center of the motor end cover (1) is provided with a bearing seat mounting hole (13); a bearing room (21) with the circumferential wall of the motor end cover (1) as a coaxial machining datum is formed in the bearing seat (2); and the bearing seat (2) is inserted in the bearing seat mounting hole (13). According to the motor disclosed in the invention, through the motor end cover and the bearing seat which are independent mutually, the assembly coaxial accuracy between the bearing seat and the motor end cover can be effectively ensured, and the electromagnetic noise of the motor is thus reduced.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor end cover assembly and a motor. Background technique [0002] In the motor industry, the motor end cover is usually formed by stretching the sheet material. Although the motor end cover formed by stretching the sheet material has the advantages of fast and efficient production, the stator and rotor are prone to appear after the motor is assembled. The problem of insufficient coaxial precision between the stator and the rotor causes the unevenness of the air gap between the stator and the rotor to become larger, resulting in a large electromagnetic noise generated by the motor. When the coaxial precision is seriously insufficient, there may even be direct friction between the stator and the rotor, resulting in failure of the motor and greatly reducing reliability. [0003] Therefore, at this stage, further structural optimization of the motor end cover is required to solve...
