Six-phase magnetism-concentrating internal and external passive rotor transverse flux permanent magnet motor

Abstract

The invention discloses a six-phase magnetism gathering-type internal and external passive rotor transverse flux permanent magnet motor, which comprises a stator formed by Chinese wang-shaped stator iron cores and Chinese wang-shaped permanent magnets, an internal rotor iron core, an external rotor iron core and an armature coil, wherein the permanent magnets are magnetized in a circumferential direction, the magnetization directions of adjacent two permanent magnets are opposite, armature windings are wound in grooves formed by alternate arrangement of the stator iron cores and the permanentmagnets, the stator is formed by three unit structures uniformly arranged along the circumference, each two phases is a unit structure, each of the internal rotor iron core and the external rotor ironcore is provided with three circles of rotor teeth arranged along the axial direction which are connected as a whole through a ring column, and the adjacent two circles of the rotor teeth are offsetby a mechanical angle of 180 / n degrees. When the armature winding is linked with the maximum permanent magnet flux linkage, the stator teeth and the rotor teeth are completely coincident, the permanent magnets adjacent to the same Chinese wang-shaped stator iron core together advance to the Chinese wang-shaped stator iron core along the circumferential direction for magnetism gathering, each permanent magnet provides an effective magnetic motive force, the magnetic circuit can travel in both directions of the internal and external rotors through a radial air gap, and the permanent magnet utilization rate and the torque density are improved.

Description

Technical field [0001] The present invention relates to a hexagonal magnetic internal and external passive rotor lateral magnetic flux permanent magnet motor, belonging to the technical field of transverse magnetic flux motors. Background technique [0002] The landscape magnetic flux motor structure is proposed by German professor Herbert WEH proposed in the early 1980s, which can fundamentally increase the torque density. Among the traditional permanent magnet motors, the stator tooth groove is in the same section, and if the coil cross-sectional area is increased, the width of the teeth is reduced, and the magnetic flux is reduced, and the tooth size is constrained. The stator teeth and armature coils of the transverse flux permanent magnet motor are perpendicular to each other, and the width and coil cross-section are decoupled independently of each other, magnetic circuit and circuit decouple, so higher torque density and power density can be obtained. For wind power, electr...
