Motor

Abstract

The invention provides a motor, which comprises a stator assembly and a rotor assembly, wherein the rotor assembly is located at an axial end of the stator assembly; the stator assembly is provided with a plastic package part and a circular terminal plate; the terminal plate is plastically packaged into the plastic package part; the plastic package part is plastically coated with a plurality of stator poles uniformly in the circumferential direction; the rotor assembly is located at the axial end of the stator assembly; and the circular terminal plate is plastically packaged into the plastic package part, so that the axial thickness of the motor is reduced and the ultrathin target of the motor is achieved. Therefore, the motor is small in overall volume, light in weight, simple in structure, low in production cost and high in cost performance.

Problems solved by technology

[0003] The current market applications are mainly permanent magnet brushless DC motors with traditional radial magnetic fields, such as figure 1 As shown, the existing permanent magnet brushless DC motor 1 adopts a radial magnetic field, the stator assembly 11 is at the outer end, the rotor assembly 12 is in the inner circle, and the bearing 13 on the rotor assembly 12 is fixed by the end covers 14, 15 at both ends. The iron core and structural characteristics lead to the inevitable increase of the axial thickness of the motor 1, which makes the volume of the motor 1 larger

In addition, the stator assembly 11 is connected through the circular terminal board 16, and the axial thickness of the motor 1 is increased, so that the overall cost of the motor 1 is high and the cost performance is low.
