Abstract
Aspects of the invention relate to a switched reluctance motor and the reduction of motor torque output ripple by inclusion of flux barriers. The inclusion of flux barriers running parallel to the motor shaft axis located in the appropriate places in either or the rotor and stator can modify the torque profile output of the motor markedly reducing potential vibration problems in a vehicle driveline.
