The transverse flux motor is different from a radial flux motor and an axial flux motor which are in the traditional structures, and magnetic lines of force in the transverse flux motor are distributed in a three-dimensional mode and have high torque density. The outer rotor transverse flux motor is a structural form of a transverse flux motor and is generally used for a hub motor of an electric vehicle.
The traditional hub motor is generally an outer rotor radial flux motor, the rotor of the hub motor is convenient to manufacture, but the winding of the stator is difficult. Each phase of the outer rotor radial flux motor is provided with a plurality of grooves in the circumferential direction, and each groove is separately embedded with wires during coil winding, so that the winding mode is complex, and particularly when the number of poles of the motor is large, the winding difficulty can be greatly increased. For example, in the hub motor for the electric vehicle in which three-phase stator windings are arranged along the circumferential direction, the stator adopts a more-slot structure to be matched with the rotor, the complexity of stator winding is increased sharply due to the increase of the number of slots, the working hours of coil assembly are long, and mechanical equipment is expensive, so that the number of poles of the traditional outer rotor radial flux motor cannot be increased.
Because the magnetic circuit of the transverse flux motor is a three-dimensional structure, the traditional stator structure is generally formed by laminating silicon steel sheets, the silicon steel sheets are two-dimensional magnetic circuit materials, and the three-dimensional magnetic circuit structure manufactured by the two-dimensional magnetic circuit materials is difficult to realize.

In addition, in the radial direction, the space closer to the center of the circle is smaller, and the space farther from the center of the circle is larger, so that the silicon steel sheets must be laminated along the circumferential direction in order to realize the three-dimensional magnetic circuit after the silicon steel sheets are laminated, and thus, the space close to the inner side in the radial direction is occupied and then a gap is formed at the position close to the outer side, so that the space utilization rate in the motor is not high, the magnetic flux path is narrow, the magnetic circuit is easy to saturate, and the load capacity of the motor is low.
And the other stators are formed by laminating silicon steel sheets, a three-dimensional magnetic circuit motor is manufactured by pure two-dimensional magnetic circuit materials, the manufacturing process is complex, and the whole stator needs to be encapsulated and fixed. And in order to ensure the realization of a three-dimensional magnetic circuit, the stator yoke part adopts a method of splicing silicon steel sheets along the circumferential direction. The motor stator yoke manufactured by the method has the advantages of complex structure, high manufacturing difficulty and space waste, the magnetic flux on the stator teeth on the two sides of the coil is difficult to be perfectly connected with the yoke, the magnetic flux path is narrow, the magnetic circuit is easy to saturate, the magnetic flux of the stator is reduced, the load capacity of the motor is influenced, and the output of the motor is limited.
In addition, the transverse flux motor in the prior art is generally a three-phase motor, namely three-phase stators are sequentially arranged along the axial direction, and the winding adopts a structure of three coils, so that the difficulty of three-phase manufacturing and assembling is high.
