Abstract

The invention discloses a transverse flux motor stator and rotor assembly and a transverse flux motor, and belongs to the field of motors. The transverse flux motor stator and rotor assembly comprises an outer rotor assembly and a stator assembly. The stator assembly comprises multiple phases of stator modules, each phase of stator module comprises two stator toothed plates and a stator yoke ring, and a coil wound around the axial direction as the center is arranged between the two stator toothed plates. The outer rotor assembly comprises a rotor yoke ring, the inner surface of the rotor yoke ring is provided with a plurality of rows of magnetic steel distributed in the axial direction, the number of the rows of the magnetic steel is the same as the number of phases of the stator modules, the magnetizing direction of the magnetic steel is the radial direction, and the number of the magnetic steel in each row is two times of the number of stator teeth on one stator toothed plate. The magnetic field directions of the two pieces of adjacent magnetic steels in each row are opposite, and the magnetic field directions of the two pieces of adjacent magnetic steel in the adjacent row are the same. A three-dimensional magnetic circuit structure is realized by combining the silicon steel sheet stator toothed plates and the SMC stator yoke rings, the manufacturing difficulty is low, the working time and the cost are low, the coil winding is convenient, more poles can be manufactured, and the torque pulsation of the motor is reduced.

Description

technical field [0001] The invention relates to the field of motors, in particular to a transverse flux motor stator and rotor assembly and a transverse flux motor. Background technique [0002] The transverse flux motor is different from the radial flux motor and the axial flux motor of the traditional structure. The magnetic force lines inside the transverse flux motor are three-dimensionally distributed and have a high torque density. The outer rotor transverse flux motor is a structural form of the transverse flux motor, which is generally used in the hub motor of electric vehicles. [0003] The traditional in-wheel motor is generally an outer rotor radial flux motor, the rotor of which is easy to manufacture, but the winding of the stator is relatively difficult. Each phase of the outer rotor radial flux motor has multiple slots in the circumferential direction, and each slot is individually embedded when winding the coil. Such a winding method is more complicated, esp...

Problems solved by technology

The structure of the motor stator yoke made by this method is complicated, the manufacture is difficult, and the space is wasted. It is difficult to achieve a perfect connection between the magnetic flux on the stator teeth on both sides of the coil and the yoke. The stator flux is reduced, the load capacity of the motor will be affected, and the output of the motor will be limited
