THE RADIAL MAGNETIC COUPLING STUDIES BETWEEN MAGNETIC GEARS

The torque of the radial magnetic coupling between magnetic gears with different magnetic poles has been investigated by experimental and co mputer simulation analyses. The torque of magnetic coupling is sensiti ve to the number of magnetic poles, and it decreases with increasing t he 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 s imulation calculated values of the torque of magnetic coupling by both the virtual work technique and Maxwell stress tensor method are in ex cellent agreement with the experimentally measured values.
