Abstract
A rotor for a permanent magnet motor of the interior or embedded magnet type employs permanent magnet material in slots of two different widths in the rotor to bring the motor up to synchronous speed through hysteresis loss. During rotor rotation, the permanent magnet material in the thinner slots is driven completely about its hysteresis loop while the material in the wider slots experiences no polarity reversals.
