Abstract
Provided is a rotary electric machine that can reduce torque ripple. A stator core of the rotary electric machine is formed by combining, in the axial direction, a plurality of kinds of stator core portions having different tooth end shapes. Thus, phases of torque ripples occurring in the respective stator core portions become different from each other, so that torque ripple of the entire motor can be suppressed more efficiently.
