Abstract
An analytical method by Schwarz-Christoffel (SC) transformation has been proposed for calculating the relative permeability, which can accurately reflect the cogging effect on the air gap flux density. The cogging force and cogging torque of the linear-rotary-permanent magnet actuator (LRPMA) can be predicted by this method to consider the slotted stator and slotted rotor. The simulation validates the correctness and accuracy of the computing relative permeability method.
