Embodiment 1

[0065] This embodiment provides a motor, such as figure 1 , figure 2 As shown, it includes: a housing 1, including a seam 2 and an end cap 4 for closing the seam 2; The first part and the second part, the first part and the second part interfere with each other, so that the first part and the second part are relatively stationary in a first direction, and the first direction is parallel to the direction of the housing 1 central axis, and the first direction is directed from the housing 1 to the end cover 4; the second fixing assembly includes the first split body and the The second split body, the first split body and the second split body interfere with each other, so that the first split body and the second split body are relatively stationary in a second direction, and the second direction is parallel to the The direction of rotation of the rotor inside the housing 1. During the working process of the motor, due to the continuous rotation of the internal rotor, the end ...

Abstract

The present invention provides a motor, comprising: a housing, including a seam and an end cover for closing the seam; a first fixing assembly, including a first part and a second part respectively located on the end cover and the housing and cooperating with each other. One part and the second part interfere with each other, so that the first part and the second part are relatively stationary in the first direction, the first direction is parallel to the central axis of the housing, and the first direction is directed from the housing to the end cover; the second fixing component, It includes a first split body and a second split body that are respectively located on the end cover and the housing and cooperate with each other. The first split body and the second split body interfere with each other, so that the first split body and the second split body are opposite in the second direction At rest, the second direction is parallel to the rotation direction of the rotor inside the housing. Even if the assembly method of interference fit is not adopted, the cooperation stability of the shell and the end cover during the operation of the motor can be guaranteed. This in turn eliminates the problem of easy damage due to disassembly due to interference fits.

Description

technical field [0001] The invention relates to the technical field of motor structure, in particular to a motor. Background technique [0002] The plastic-encapsulated motor is a motor in which the stator core and winding of the motor are packaged with engineering plastics using plastic packaging technology. [0003] The plastic-encapsulated motor includes a housing, and one end of the housing is integrally formed with the stator inside the housing by injection molding of a plastic sealing compound, so as to realize the integration of the housing, the stator, and one end of the plastic seal. The other end of the shell is not open and is usually closed by an end cap. [0004] Since the motor will vibrate during operation, in order to ensure that the end cover remains closed. Therefore, the binding force between the end cover and the housing needs to meet certain requirements, so as to prevent the end cover from loosening caused by vibration during the motor operation.
