Abstract

See full text

An axial-type rotary electric machine that improves a torque and an efficiency relative to a size of a rotor is provided. The axial-type rotary electric machine is provided with a stator having a stator core, and a rotor facing the stator along an axial direction of a rotation axis passing through the stator. The rotor includes a permanent magnet arranged so as to face the stator core in the axial direction of the rotation axis, a yoke arranged so as to face the stator core across the permanent magnet, and a support member supporting the yoke. The support member includes a protrusion protruding so as to face a side surface of the permanent magnet that is on the farther side to the rotation axis. In projection along the axial direction of the rotation axis, a first region where a projecting portion of the permanent magnet does not overlap a projecting portion of the yoke is formed in the permanent magnet, and the first region is formed on the outer-diameter side of the permanent magnet and the first region is formed on a side of the protrusion.
