A generated energy is increased in a low-rotation region with an engine rotation kept stabilized. An engine rotating speed judging unit (48) detects the rotating speed of a rotor, and, when an engine's rotating speed is in a low-rotation region, a driver (46) subjects a rectifier (4) to delay angle energizing control to intensify a field magnetic flux and increase a generated energy. The driver (46) responses to a change in the polarity of a magnetic pole detected by a rotor angle sensor (29), and reads a delay amount stored in a delay angle amount setting unit (49) to subject a stator winding to delay angle energizing. The output voltage of the generator is so controlled as to converge to a value between voltage control values Vmax and Vmin lower than the regulated voltage of a regulator. |
