Abstract

The invention provides a stator component and a plastic package motor. The stator component comprises an insulating skeleton (1), a supporting plate (2) and a circuit board (8), and the supporting plate (2) is arranged between the insulating skeleton (1) and the circuit board (8) and supports the circuit board (8). The stator component according to the invention can effectively reduce or avoid thedeformation of the circuit board due to heating or extrusion in an injection molding process so as to improve the reliability of the motor.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a stator assembly and a plastic-encapsulated motor. Background technique [0002] Motors are widely used in various electrical equipment in industrial production and life. Common motors include DC brushless motors and AC plastic-encapsulated motors. Existing motors all have a stator and a rotor that rotates relative to the stator. The rotor shaft is installed in the rotor and rotates with the rotation of the rotor, thereby outputting power. [0003] In the current plastic-encapsulated motor, many circuit boards are placed inside the motor for injection molding, but the circuit board is easily deformed by heat and pressure during the injection molding process, which will affect the components on the circuit board and reduce the performance, which in turn will lead to the performance of the circuit board. Reduced, greatly affecting the reliability of the motor. Conten...
