Abstract
Provided is a pole-number-changing rotary electric machine having excellent torque-current characteristics both at a more-pole drive time and at a less-pole drive time without use of a winding changing mechanism. The pole-number-changing rotary electric machine is configured to change a number of poles between the more-pole drive time and the less-pole drive time, and includes: a rotary electric machine including: a stator including stator slots arranged in a mechanical angle direction; and a rotor configured to be rotated by magnetomotive forces generated by currents flowing through stator coils stored in the stator slots; an inverter configured to supply an m-phase current to the stator coils; and a control unit configured to control the inverter, the per-stator-slot magnetomotive forces being arranged at regular angle intervals.
