Abstract

An object of the present invention is to provide a motive power output apparatus including a motor with a permanent magnet and a motor without a permanent magnet. A boost device (10) is connected to a power storage device (B). A first drive device (30) is connected to the boost device (10). A first rotating electric machine (35) with a permanent magnet is connected to the first drive device (30). A second drive device (40) is connected to the power storage device (B). A second rotating electric machine (45) without a permanent magnet is connected to the second drive device (40). A third drive device (20) is connected in parallel to the first drive device (30). A third rotating electric machine (25) with a permanent magnet is connected to the third drive device (20). The second rotating electric machine (45) is formed of a reluctance motor or an induction motor. The first rotating electric machine (35) and the second rotating electric machine (45) of the present invention may be linked to wheels of a vehicle.
