Abstract

A hybrid magnetic field controllable axial flux motor comprises two amorphous alloy stators and a rotor arrange between that two stators; The stator core of stator is divided into three parts along the radial direction, which are stator core in permanent magnet region, stator core in magnetic isolation region and stator core in electric excitation region. The armature winding of the permanent magnet region is arranged on the stator core of the permanent magnet region; The armature winding of the electric excitation region is arranged on the stator core of the electric excitation region; A permanent magnet and a ferromagnetic pole are embedded on the rotor bracket of the rotor part, respectively corresponding to the stator iron core of the electric excitation region and the stator iron coreof the permanent magnet region in the axial direction. The utility model has the advantages of simple manufacture, low loss, high power density and wide range of weak magnetic field expansion speed.

Description

technical field

[0001] The invention belongs to the field of axial flux motors, and mainly relates to a composite excitation amorphous alloy axial flux motor. Background technique

[0002] As a new type of soft magnetic material, amorphous alloy strip has excellent magnetic properties, corrosion resistance, wear resistance, high strength, high hardness and high resistivity, and its thickness is only 0.025mm. Compared with the traditional silicon steel sheet, the amorphous alloy has very small core loss especially in the high frequency range, so the amorphous alloy strip is very suitable for high-speed high-frequency motors. The traditional amorphous alloy axial flux permanent magnet synchronous motor adopts the permanent magnet structure of double rotor and single stator. The surface of the motor rotor with this structure is covered with permanent magnets, and the stator is covered with armature windings on both sides, which has high power density. , high torque density and...
