An interior permanent magnet synchronous motor (IPMSM) has high efficiency and torque because the motor utilizes both magnetic torque and reluctance torque, because of the locations of permanent magnets in the rotor. The IPMSM has many applications, such as in electrical household appliances, in office automations and in electrical vehicles. Establishment of the optimum design for an IPMSM is thus important. Here, we present one calculation method for the dynamic characteristics of an IPMSM with concentrated winding based on the magnetic circuit model. In this model, the magnetic circuit of the IPMSM is expressed by variable reluctances and permanent magnet magnetomotive forces (MMFS) changing with rotor angle. In order to obtain the reluctances and permanent magnet MMFs, we calculate fluxes passing through a stator pole using the finite element method (FEM). Using the proposed model, we can easily calculate dynamic characteristics of the IPMSM.
