A permanent magnet synchronous motor includes a permanent magnet rotor and a stator having wound teeth facing the rotor. The stator teeth each include notches having equal width and having a spacing also equal to the notch width. Further, each adjoining two teeth are separated by a gap having a width equal to the width of the notches on the teeth. The permanent magnet synchronous motor thus configured provides substantial reductions in reluctance torque, or "cogging torque" over prior art permanent magnet synchronous motors. Further, the frequency of the reluctance torque is increased, a desirable condition, with respect to prior art permanent magnet synchronous motors.
