Abstract

See full text

The rotary electric machine includes: a rotor core configured having electromagnetic steel sheets; a stator core having electromagnetic steel sheets; a magnet inserted in each of a plurality of through holes; and a magnetic end plate in contact with one or each of an end surface on one side in the axial direction of the rotor core and an end surface on another side in the axial direction of the rotor core, and having a single magnetic sheet or a plurality of magnetic sheets stacked in the axial direction, wherein heat generated from the magnetic end plate owing to eddy current that is generated in the magnetic end plate by magnetic flux from the stator core is equal to or lower than heat generated from the rotor core owing to eddy current that is generated in the rotor core by magnetic flux from the stator core.
