摘要： An electric motor is equipped with a rotor having multiple rows of slits arranged along a radial direction. A permanent magnet is buried only in some of the slits, namely the ones closest to the center of the rotor or the innermost slits, to drive the motor using both magnet torque and reluctance torque. This improves the torque output.
