ABSTRACT:
The rotary machine is composed of the rotor having magnetic poles and the stator having the stator yoke portion constituting the iron core tooth portion wound by the stator winding and the flux flow path of the magnetic poles. The rotor is composed of a metallic material having ferromagnetic parts and non-magnetic parts as a member and has a magnetic barrier area composed of the slit portion for blocking the bypath magnetic path in the periphery of the rotor and the non-magnetic parts. The rotary machine that produced torque can be increased sufficiently and the mechanical strength during high-speed running is improved and an electrical vehicle using it.
