Problems solved by technology

[0004] However, the power line of the PG circuit board needs to be led out of the stator, which makes a gap between the power line, the stator and the cover plate (bearing bracket or end cover, etc.) on the stator
At present, the sealing method of the power cord of the plastic-sealed motor is mainly to set a sealing sleeve outside the thermoplastic sleeve of the power cord. Risks such as uneven air gap and even jamming of plastic-encapsulated motors have seriously affected the normal working performance and service life of plastic-enclosed motors

Abstract

The invention discloses a plastic package motor and a stator assembly thereof. The stator assembly comprises a stator (4), a cover plate (1) and a circuit board (2), a groove (6) is formed in the stator (4), a power line (3) of the circuit board (2) is located in the groove (6) and makes contact with the inner side face of the cover plate (1); seal ribs abutting against the power line (3) are arranged in the groove (6). According to the stator assembly, by means of the arrangement, the power line, the cover plate and the groove are in close fit under the action of contact force between the seal ribs and the power line, pressure exerted on the power line by the cover plate and own tension of the power line, gaps are avoided, it is avoided that ants and other tiny organisms enter the motor and the motor is uneven in air gap and is stuck, the normal work performance of the motor is improved, and the service life of the motor is prolonged.

Description

technical field [0001] The invention relates to the technical field of motor equipment, in particular to a plastic-encapsulated motor and a stator assembly thereof. Background technique [0002] As a type of motor, the plastic-encapsulated motor has been widely used. [0003] At present, in plastic-encapsulated motors, PG circuit boards are generally used to sense the speed of the motor and output it. Among them, the PG circuit board is assembled with the stator of the plastic-encapsulated motor to form a stator assembly. [0004] However, the power line of the PG circuit board needs to be led out of the stator, which causes a gap to be formed between the power line, the stator and the cover plate (bearing bracket or end cover, etc.) on the stator. At present, the sealing method of the power cord of the plastic-sealed motor is mainly to set a sealing sleeve outside the thermoplastic sleeve of the power cord. Risks such as uneven air gaps and even jamming of plastic-encaps...
