An analysis of the drive performance of magnetic field modulation type permanent magnet reduction gear

To improve the transmission performance of magnetic field modulation type permanent magnet reduction gear, 1J22, a new material, was applied to the magnetic adjusting ring. The finite element software was used to simulate and analyze the permanent magnet reduction gear using a silicon steel sheet and 1J22 magnetic adjusting ring materials. The effect of changing the material on its air gap magnetic density and output torque was studied. The results indicate that using 1J22 as a magnetizing ring material can improve the strength and output capacity of the air gap magnetic field, and improve the transmission performance of magnetic gears modulated by magnetic fields.
