Surface mounted permanent magnet synchronous machines (SM-PMSMs) have been extensively developed due to their high power density and efficiency, good performance In surface permanent magnet (PM) machines, for example, it is believed that the rotor length should be nearly the same as the rotor diameter.Optimizations were performed for maximum flux density, maximization of magnetic energy vs. magnet cost, and maximization of torque. One of the important challenges in design of the PM electrical machines is to reduce the cogging torque.In this method the machine magnets consist of several identical segments which are shifted to a definite angle from each other.
