Abstract

In this paper, we analyze the characteristics of electecromotive force(emf), phase current and torque according to the length of the air gap using 2nd order FEM(Finite Element Method) in Synchronous Reluctance Motor(SRH) and Brushless DC Motor(BLDC) with same volume and size. In the analysis with FEM, we applied the time-step function considering the motor switch in the magnetic vector potential of the unknown node.
