Ultrathin high-power direct current magnetoelectric motor

Abstract

The invention discloses an ultrathin high-power direct current magnetoelectric motor, comprising a transmission shaft, a discal stator component sleeved at the middle section of the transmission shaft, discal rotor components which are respectively arranged at the two sides of the stator component and rotate with the transmission shaft, and an upper end cap and a lower end cap which are respectively arranged at the two sides of the rotor components. The stator component comprises a discal stator frame, a plurality of fan-shaped grooves which are arranged on the stator frame in a ring form, fan-shaped windings arranged in the fan-shaped grooves, and inner clamping rings and outer clamping ring for fixing the fan-shaped windings. The rotor component comprises a rotor plate fixedly connectedwith the transmission shaft, fan-shaped grooves which are arranged on the rotor plate in a ring form, and permanent magnets fixed in the grooves. The surface of the rotor plate, which provided with the permanent magnets, faces the fan-shaped windings. The motor of the invention has the advantages of higher efficiency and energy saving, and the manufacturing, the assembling and the maintenance of the stator winding are more simple, convenient and reliable.

Description

technical field [0001] The invention relates to a DC motor, in particular to an ultra-thin and high-power DC permanent magnet motor. Background technique [0002] The ultra-thin motor is a disc motor. The characteristics of this type of motor are: small size, light weight, compact structure, and relatively thin, also known as a disc motor. Disk motors usually have a stator with two rotors sandwiched between them. There are two structures of the stator, one is a metal structure, and the other is a coreless structure (injection or injection molding structure). The metal structure is generally rolled and pressed into a disc shape by silicon steel sheet to limit the radial magnetic flux, and the winding is fixed on the silicon steel sheet or in the groove. With this structure, during the operation of the motor, the two rotors generate a strong alternating magnetic field in the axial direction, and the metal conductor will form a large short-circuit current (commonly known as "...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the unreasonable forming process of the stator winding of the existing disc motor, the power of the ironless motor cannot be increased, and to break through the limitation that the power of the existing ironless disc motor can only be made very small, and to provide a More efficient, energy-saving, ultra-thin high-power DC permanent magnet motor with simpler and more convenient stator winding production, assembly and maintenance
