Abstract

The invention discloses an axial permanent magnet motor of dual magnetic circuit magnetic modulation type, which comprises a coaxially installed first rotor, a first magnetic modulation ring, a first stator, an inner rotor, a second stator, and a second magnetic modulation ring , the second rotor. Both the first rotor and the second rotor include a rotor yoke, and a Halbach permanent magnet array arranged along the circumference on the inner surface of the rotor yoke. The double magnetic circuits are the magnetic field circuit formed between the outer rotor, magnetic ring, stator and inner rotor, and the magnetic field circuit formed between the outer rotor, magnetic ring, and stator, which enhances the magnetic modulation performance. The present invention also increases the magnetic adjustment tooth, and adjusts the double magnetic circuit through the magnetic adjustment tooth. The fixed bracket of the magnetic adjustment gear includes two layers of inner and outer layers along the circumference, and its structure is light and firmer. At the same time, the addition of the fixed bracket enables the heat on the magnetic adjustment ring to have a larger heat dissipation area and is easier to cool.

Description

technical field [0001] The invention relates to an axial permanent magnet motor with dual magnetic circuit magnetic field adjustment, and belongs to the technical field of permanent magnet motors. Background technique [0002] In recent years, electric vehicles have attracted much attention as an emerging industry. Because they are beneficial to solve problems such as limited oil resources and aggravated air pollution, they have also become a very important strategic research industry in my country. The three most important key technical links of electric vehicles focus on: battery, motor and drive. In the absence of fundamental breakthroughs in battery technology, the development of efficient and reliable motors has become the main goal of experts and scholars from all over the world. The axial permanent magnet motor has attracted extensive attention due to its advantages of high torque / power density, excellent heat dissipation performance and compact structure, and axial ...
