Abstract

Specific torque and bearing reaction forces are simulated for two models of axial flux magnetic gears. The models cover simulation in two scale ranges: hundreds of microns and tenths of microns. The simulations presented are performed considering currently available magnetic properties in the microscale and potentially achievable ones. Specific torque of the models is between 2.76 up to 8.24 Nm/kg. This range is large enough to overpass conventional toothed microgear specific torque. This means that micro magnetic gears can not only provide conversion of speed and torque without friction but also to be more compact.
