Rotating electric machine

摘要

An electric rotating machine capable of enlarging the operational range is provided. A tooth portion 30 of a stator is divided into a first tooth portion 31 and a second tooth portion 32 in a relatively movable manner between a first position in which the magnetic resistance between the first and second tooth portions 31 and 32 is small and a second position in which the magnetic resistance is relatively large. In a state in which the second tooth portion 32 is in the second position, a region from a stator yoke portion side end of the current-carrying winding to a rotor side end of the winding arrangeable region is divided into a first region A1 and a second region A2. A current-carrying winding space factor in the first region is set to be relatively smaller than in the second region.
