Motor stator sealing structure

Abstract

The utility model discloses a motor stator sealing structure, which comprises a stator body, a sealing cylinder is inserted in an inner hole of the stator body in a fitting manner, and the sealing cylinder and the stator body are encapsulated into a whole. According to the motor stator sealing structure, the sealing cylinder is arranged in the inner hole of the stator body, so that the motor stator can be effectively isolated from the interior of the cavity, and a sealing form is formed. At the moment, sealing of the motor stator is completed by the sealing cylinder, and the pouring sealant only plays a role in supporting and bonding the sealing cylinder, so that sealing failure cannot be caused even if tiny air holes exist in the pouring process. Moreover, the sealing cylinder and the motor stator are integrally formed, so that the occupied space can be saved, and the overall size of the equipment is reduced.

[0006] In the motor stator sealing structure of this utility model, the sealing cylinder includes a cylinder body, and an inwardly extending inner cylinder edge and an outwardly extending outer cylinder edge are integrally formed at both ends of the cylinder body.

[0007] In the motor stator sealing structure of this utility model, the outer wall of the cylinder is provided with an axial positioning step that corresponds to and cooperates with the inner hole of the stator body.

[0014] In the motor stator sealing structure described in this utility model, a sealing cylinder is installed in the inner hole of the stator body, which effectively isolates the motor stator from the cavity interior, thereby forming a seal. In this case, the sealing of the motor stator is accomplished by the sealing cylinder, and the potting compound only serves to support and bond the sealing cylinder. Therefore, even if there are minor air bubbles during potting, it will not cause seal failure.
