<p>PROBLEM TO BE SOLVED: To provide a power generator for internal combustion engine provided with a function which prevents the fluctuations of the number of revolutions of an internal combustion engine. SOLUTION: A power generator for internal combustion engine incorporates a fluctuation detecting section 301 which detects the fluctuation of the number of revolutions of an internal combustion engine, a torque converting section 302 which converts the detected fluctuation of the number of revolutions of the engine into torque fluctuations, and a low rotation speed discriminating section which discriminates that the engine is operating at a low rotating speed. The generator also incorporates a speed deciding section 300, which decides the speed Nd of a rotating magnetic field generated from three-phase field coils 11 of a rotor 1R as a function of the torque fluctuation found by means of the torque conversion section 302 and a rotating magnetic field generating section 21, which generates the rotating magnetic field of the decided speed Nd from the field coils 11 of the rotor 1R.</p> |
