Abstract
Disclosed is a radial-axial air gap three-phase disc-type transverse flux permanent magnet motor. Each phase includes a stator consisting of shoe-shaped stator cores and shoe-shaped permanent magnets, and a radial-axial rotor. The permanent magnets are magnetized in the circumferential direction, and the magnetization directions of the two adjacent permanent magnets are opposite to each other. Armature windings are wound in the grooves formed by the alternately arranged stator cores and the permanent magnets. The radial-axial rotor includes radial teeth, axial teeth, and right-angled yokes. The radial teeth are connected to the axial teeth through the right-angled yokes. Adjacent radial/or axial teeth are spaced at a mechanical angle of 360/n degrees. Radial teeth and the adjacent axial teeth under the same pole pairs are spaced at a mechanical angle of 180/n degrees, where n is the number of pole pairs of the radial-axial air gap three-phase disc-type transverse flux permanent magnet motor.
