Rotary machine and electrical vehicle using the same

摘要

The rotary machine 1 is composed of the rotor 3 having magnetic poles and the stator 4 having the stator yoke portion 41 constituting the iron core tooth portion 42 wound by the stator winding 5 and the flux flow path of the magnetic poles. The rotor 3 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 72 for blocking the bypath magnetic path in the periphery of the rotor and the non-magnetic parts 75. 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.
