Abstract:
A hybrid vehicle comprising:an internal combustion engine; a battery which stores and discharges electric power; an electric rotary machine mechanically connected with a crankshaft of said internal combustion engine for starting up said internal combustion engine by the electric power supplied from said battery, and generating an electric power by revolution of said internal combustion engine to charge said battery; an inverter for controlling driving and generating of said electric rotary machine; and a controller for controlling said inverter; wherein said electric rotary machine is formed with a stator having a winding and a rotor rotatably disposed and separated from said stator by a gap; said rotor is divided along the direction of the axis of rotation into two-piece parts; said two rotor piece parts have respective field magnets whose polarities differ from each other, and are alternately arranged mutually with respect to a direction of rotation; one of said two rotor piece parts has a mechanism for varying a relative rotation-axis directional position with respect to the other of said two rotor piece parts, depending on an equilibrium of a magnetic interaction force between the field magnet of one of said two rotor piece parts and the field magnet of the other of said two rotor piece parts and a torque direction of the rotor.
