Rotating Electric Machine

Abstract

A rotating electric machine includes a rotor including a rotor core configured by laminating a plurality of electromagnetic steel plates and a shaft that supports the rotor core, a stator that faces the rotor via an air gap that is a predetermined space, on a radially outer side of the rotor, and a housing that houses the rotor and the stator, in which the housing forms an air flow passage between the rotor and the stator, the shaft includes a shaft flow passage that communicates with the air flow passage, and the rotor includes a pump that is coupled to the shaft and is synchronized with rotation of the shaft and a radial direction flow passage that communicates the shaft flow passage with the air gap.
