Abstract :
The paper presents a method to determine hysteresis losses in synchronous permanent magnet (PM) slotless motors. The method comprises four steps : (1) experimental determination of the B-H loop, (2) analytical modeling of the B-H loop by applying different models, (3) analytical modeling of the hysteresis losses, and (4) determination of the hysteresis losses in a synchronous PM motor, and results verification using an experiment and an FEM software. This paper also presents an innovative and simple way to take into account the effect of saturation when solving the Laplace equation.
