Abstract
A radial gap type rotating electrical machine includes a field and an armature. The field includes a permanent magnet and a magnetic ring which serves as a back yoke of the permanent magnet. The magnetic ring is provided at a position farther from the armature than the permanent magnet, and includes a recess at a magnetic pole center. The magnetic pole center is a center of a magnetic pole in a circumferential direction with respect to a rotation axis. A thickness of the recess in the radial direction around the rotation axis as a center comes to locally thin.
