Abstract :
An accurate modeling of permanent magnet synchronous motor (PMSM) is necessary for precise torque control and/or high efficiency drive control. This paper discusses the mathematical model of PMSM taking account of losses of all kinds, that is, the copper loss, iron loss, mechanical loss, and stray loss. A precise torque equation is presented in this paper. In addition a measurement method for the losses is also presented. The validity of the proposed mathematical model is confirmed by the comparison between the theoretical torque obtained by the model and the actual torque
