Abstract :
This paper investigates a novel axial magnetic gear using ferrite magnets. In order to increase the air-gap flux density the ferrite magnets are arranged in flux focusing configuration. The simulation results presented in this paper indicate that a relatively high torque density can be achieved when using only ferrite magnets.
