This abstract first appeared for US patent application 18486614 titled 'ELECTRIC MOTOR ROTOR WITH CIRCULATED AIR COOLING
Original Abstract Submitted
A rotor for an electric machine includes an air circulation cooling system. The rotor includes a rotor core having cavities internal to the rotor core. The rotor core extends longitudinally between two ends. The cavities are defined by the rotor core. The cavities extend through the rotor core and open through at least one of the ends. The rotor core operates to circulate air through the cavities by rotation of the rotor core.
