Abstract

A modular multilayer disc type motor based on an effective magnetic domain technology is composed of multiple kinetic energy converting units which are sequentially and axially aligned and superposed, wherein each kinetic energy converting unit is formed by disk rotors and contiguous disk rotor windings of multiple permanent magnets fixed on one disk face, and permanent magnet bodies on the rotors are identical in shape and axially aligned. At least two groups of kinetic energy converting units are installed within an axial distance of the length. The length is 12-14 times of the thickness of the permanent magnet bodies. Structural basic parameters of the disc type motor are confirmed. The using efficiency of the disc type motor in a structural parameter range is at least 20% higher than that of a column type motor.

Description

technical field [0001] The invention relates to generator or motor technology, in particular to a modular multi-layer disc motor based on active magnetic domain technology. Background technique [0002] The traditional motor is a cylindrical motor, and the rotor of the inner rotor is difficult to dissipate heat. If permanent magnets are used in the rotor, there will be irreversible demagnetization at high temperature, and the performance of the motor will decrease. The situation of the outer rotor motor is opposite to that of the inner rotor motor. The heat dissipation of the stator assembly is difficult, and the stator Size is restricted. [0003] The disc motor was invented by Faraday in 1821. The stator and rotor of the disc motor are in the form of a flat disc structure, and the stator and rotor are arranged alternately in the axial direction. Limited by the material and technology level at that time, the disc motor could not be further developed. With the increasingly...
