This paper proposes an optimal rotor design method of an interior permanent magnet synchronous motor (IPMSM) by using a permanent magnet (PM) shape. An IPMSM is a structure in which PMs are buried in an inner rotor. The torque, torque ripple, and safety factor of IPMSM can vary depending on the position of the inserted PMs. To determine the optimal design variables according to the placement of the...
This paper proposes an optimal rotor design method of an interior permanent magnet synchronous motor (IPMSM) using a permanent magnet (PM) shape. The goal of this design is to obtain the minimum design variables of an objective function using a Box-Behnken response. To find the best design model, high torque and low torque ripple were found from electromagnetic finite element method, and safety factor...
This paper presents the optimal design method of cage-bars in a single-phase line-start permanent magnet synchronous motor. This method consists of two procedures. First, the basic design of cage-bars is made by analytic method of an induction motor. But, this method cannot consider nonlinear characteristic as magnetic saturation and leakage flux. Therefore, at second step, for considering the nonlinear...
