ABSTRACT:
There is provided a generator system for internal combustion engines, which can produce power efficiently at all times irrespective of the engine speed even for use in an internal combustion engine operated at variable speeds such as a vehicle engine. An AC generator electronic control unit (ACG.ECU) 3 determines a rotation speed N2 of a rotating electromagnetic field to be generated by a rotor 1R based on a mechanical rotation speed N1 of the rotor 1R in an alternator 1 such that the relative speed N of the rotating magnetic field to a stator 1S agrees with the maximum efficiency speed of rotation Nx. Then the ACG.ECU 3 sends the determined value to a rotating electromagnetic field controller 2a. The rotating electromagnetic field controller 2a controls phases of AC power to be supplied to a three-phase coil 11 of the rotor 1R to generate a rotating electromagnetic field with the rotation speed N2.
