PROBLEM TO BE SOLVED: To obtain a compact drive for vehicle by interposing a second rotor concentrically between a first rotor and a stator arranged concentrically thereto and constituting a first electric rotating machine of poles at the inner circumferential part of second rotor and the first rotor while constituting a second electric rotating machine of poles at the outer circumferential part and the stator. SOLUTION: A cylindrical rotor yoke 1311 is disposed around a rotor core 1212 through an air gap g1. A plurality of magnets 1220 are arranged at a constant interval in the circumferential direction on the inner circumferential face side. Each magnet 1220 is provided, at the opposite ends thereof, with openings 1311a for preventing leakage of flux. The magnet 1220, rotor core 1212 and a field winding 1211 constitute an electric rotating machine 1200. A plurality of magnets 1420 are arranged at a constant interval on the outer circumferential face side of the rotor yoke 1311 and provided with openings 1311a for preventing leakage of flux. The rotor yoke 1311 is provided with a stator yoke 1410 through an air gap g2. A plurality of slots in the inner circumferential face of a stator core 1412 is fitted with a field winding 1411 thus constituting a second electric rotating machine. This structure realizes a compact drive for vehicle. |
