Disc compound multi-combination three-dimensional permanent magnet motor

Abstract

The invention provides a disc compound multi-combination three-dimensional permanent magnet motor. An independent disc stator is arranged on each of a left part and a right part in an enclosure. Disc rotors are arranged on the middle parts of the independent disc stators, and permanent magnets are adhered to the left and right surfaces of the disc rotors. Spline holes in the centers of the rotors are coupled with a main power shaft through splines. Motor coil windings in lateral grooves of the disc stators take every nine grooves as a motor unit. The number of pole pairs of the motor is determined by taking each of the left and right stators as a unit to determine the number of the permanent magnets adhered to the left and right surfaces of the rotors of the motor. The structure of the conventional motor is changed, the three-dimensional space of the motor is fully utilized, and the motor has an output characteristic of high power density, the requirements of electromechanical energy conversion and low-speed high-torque driving of the motor can be met, a load can be driven under a low speed condition, the functional requirements of low speed and high torque are met, and overall efficiency is greatly improved.

Description

technical field [0001] The invention relates to a disc-shaped compound multi-combination three-dimensional permanent magnet motor. Background technique [0002] At present, the traditional column-type permanent magnet low-speed high-torque motor only meets the requirements of some functional applications. In most functional applications, the speed of the motor still requires high voltage, and the high speed is reduced to the required speed output through the gearbox. The effective area of ​​the motor cannot be fully utilized, and it cannot meet the user's requirements for low speed and high torque. Contents of the invention [0003] Aiming at the functional requirements of the traditional column type permanent magnet motor in most occasions, under the premise that the existing technology is insufficient, what the present invention aims to solve is to invent a motor with simple structure, reliable operation, small volume, light weight, less loss, low Disc-type compound mul...
