Abstract: Flat rolled magnetic steel sheets and strip or a die is turned in the press forming process. Rotor cores are stacked with turning through an angle which is an odd number multiple of about (360°/(number of slots in the motor×natural number n×2)) and stator cores are stacked with turning through an angle which is an odd number multiple of (360°/(number of poles in the motor×natural number n×2)). Stacking with turning through an angle which is an odd number multiple converts the phases of cogging torques into mutually opposite phases and cancels and reduces the cogging torque caused by magnetic anisotropy.
