Abstract: An on-vehicle rotary electric apparatus, such as an on-vehicle generator, is provided. The apparatus comprises a stator having multi-phase windings, a rotor driven to rotate by either an on-vehicle motor or the running drive shaft of a vehicle, and a driving member for driving the field winding. The rotor has a field winding producing a magnetic field. The driving member drives the field winding by supplying the exciting current thereto and changing the exciting current so that the magnetic field rotates differently in a rotation speed from the rotor. Specifically, the driving member comprises a short-circuit winding wound around part of magnetic poles of the rotor and a current-supply unit for supplying, as the exciting current, a single-phase alternating current to the field winding. The short-circuit winding produces a magnetic field delayed in phase by 90 degrees compared to the magnetic field produced by the rotor.

Abstract: A rotor of a vehicle AC generator is comprised of a rotor core and a field coil. The rotor core is comprised of a boss portion and a plurality of claw-pole portions bending to respectively extend in axial directions from outer circumferences of the boss portion to interleave with each other to form a zigzag space between the claw-pole portions. The field coil comprises a main coil portion disposed on the boss portion, a sub-coil portion disposed between the main coil and the claw-pole portions and a flywheel diode connected in parallel with the main coil. When the field current is cut off, current circulating through the main coil is increased because the energy accumulated in the sub-coil is discharged.
