Abstract
An electrical motor is provided to reduce torque ripple. Torque ripple is a variation in torque output as the rotor rotates. The motor has a stator and a rotor. The stator slots are used for windings. The rotor slots define a plurality of poles. The number of slots in the stator are equal to the number of slots in the rotor.
