Abstract :
A magnetic gear is presented that is capable of continuously varying the gear ratio in order to enable constant magnified output speed to be generated from variable input speed. A flux focusing (spoke type) inner rotor is utilized and the performance of the device is assessed when using three different stator winding configurations. In order to study the harmonics a harmonic analysis approach is outlined.
