Abstract
A technique for calculating the total losses in a skewed induction motor, based upon a multi-slice finite-element model, is presented. The ability of this model to predict the axial variation in flux-density in the motor is initially verified. The model is then used to investigate how skew affects the losses in one induction motor. It is shown that skew alters the balance between the rotor iron loss and high-frequency rotor joule loss in the machine
