technical field [0001] The invention relates to a double-sided double magnetic circuit transverse magnetic flux linear permanent magnet motor. Background technique [0002] The motion direction of the transverse flux linear permanent magnet motor is perpendicular to the plane where the motor magnetic field path is located. The motor circuit and the motor magnetic circuit are relatively independent. Compared with the traditional motor, the transverse flux motor has high torque density, flexible design, and low electromagnetic load. With the characteristics of decoupling, convenient control, and excellent low-speed characteristics, its application fields are also expanding, especially suitable for low-speed and high-power drive occasions. The transverse flux motor greatly shortens the length of the magnetic circuit, reduces the amount of ferromagnetic materials and iron loss. , within a certain range, the rate of change of magnetic energy is increased, thereby increasing the o...

Problems solved by technology

[0003] The thrust of conventional transverse flux linear permanent magnet motors can be greater than that of ordinary linear motors. However, as the thrust of the motor increases, the output force pulsation also increases. In addition, the general transverse flux linear permanent magnet motor has a complex structure and is difficult to process and assemble.

Generally, flat-plate transverse flux linear permanent magnet motors still have the problem of unilateral magnetic pull.
