摘要

This paper analyzes the effect of air-gap changes, loading currents, claw-pole and angle between driving wheel and driven wheel on electro-magnetic gears torque. ANSYS simulation result shows: torque decreases geometrically with the increase of the working air gap thickness, with the internal gear air-gap decrease with circumferential air-gap between the claw-poles, with the increase of loading current before the magnetic saturation, while it decreases rapidly with the claw-pole number, with the reduce of length-diameter ratio. It can also increase with the increase of the claw-pole thickness at the first half of the claw and the angle between driving wheel and driven wheel, but decrease with the increase of the claw-pole thickness at the second half of the claw .this is similar to the characteristic of sine.
