Abstract :
The characteristics of a permanent magnet synchronous motor are defined by airgap flux and circuit parameters. The interior permanent magnet synchronous motor (IPMSM) has nonlinear characteristics due to the structural speciality of rotor, so it is difficult to analyze circuit parameters and characteristics. This paper presents the calculation of circuit parameters by using finite element method (FEM) considering of nonlinear characteristics. Using the circuit parameters by FEM, IPMSM is analyzed and is compared with experimental values
