Motor stator assembly and motor

Abstract

The invention provides a motor stator assembly and a motor, which relates to the technical field of motor mechanical equipment and solves the technical problem that an axial magnetic field motor cannot accurately detect the position of a rotor in the prior art. The motor stator assembly comprises a stator and a controller arranged inside the stator, wherein the controller includes a main control board and a Hall plate which is in communication connection with the main control board, the main control board and the Hall plate are respectively arranged at two sides of the stator in the axial direction, the Hall plate is arranged in a mode of being closer to a rotor relative to the main control board in the axial direction of the stator, and Hall elements on the Hall plate are enabled to be arranged in a mode of directly facing a rotor magnetic ring. The motor stator assembly can realize the inductive control of the axial magnetic field motor. The Hall plate is closer to the rotor, so thatthe rotor position in operating process of the motor can be accurately detected through the Hall elements arranged in a mode of directly facing the rotor magnetic ring on the Hall plate, the detection precision of the rotor position is improved, and the stability of the motor operation is improved at the same time.

Description

technical field [0001] The invention relates to the technical field of motor mechanical equipment, in particular to a motor stator assembly and a motor. Background technique [0002] Axial field motors are also called "disk motors", that is, motors whose main magnetic field is along the direction of the rotating shaft. In recent years, axial field motors have gained increasing attention due to their compact structure, high efficiency, and high power density. [0003] The applicant found at least the following technical problems in the prior art: due to space constraints, the rotor and the controller of the axial field motor in the prior art are respectively located on both sides of the stator, and only non-inductive control can be used. However, the axial field motor using non-inductive control has the following problems: 1. Because of the non-inductive control, there is no Hall sensor, so the position of the rotor cannot be accurately detected when the motor is started, re...
