Abstract

The torque of the radial magnetic coupling between magnetic gears with different magnetic poles has been investigated by experimental and computer simulation analyses. The torque of magnetic coupling is sensitive to the number of magnetic poles, and it decreases with increasing the distance between the magnetic gears. We can increase the torque by increasing the number of poles for magnetic coupling between magnetic gears with short separation distance. The three dimensional computer simulation calculated values of the torque of magnetic coupling by both the virtual work technique and Maxwell stress tensor method are in excellent agreement with the experimentally measured values
