Abstract

PURPOSE:To reduce torque ripple as much as possible by regulating the dimensions of the outer periphery of a rotor core. CONSTITUTION:A rotor core 14 is held between permanent magnets 10. Slots 22 are formed in a stator 20, while magnetic poles are formed in a rotor 12. The ratio of the peripheral width of the outer periphery of said rotor core 14 to the width of a pitch between slid magnetic poles is set at a value between 0.75 and 0.87.
