Abstract
Object of the present invention is to provide an induction alternating current generator on vehicle and a method for generating alternating current in a generator on vehicle, which improve the efficiency of the generator by increasing magnetic flux permeating a stator core. Second electromagnetic exciting means for generating magnetic field in the direction of repelling the leak magnetic flux between neighboring claw poles, are provided in the spaces formed by the neighboring claw poles engaging each other at a gap and first electromagnetic exciting means provided inside a pair of the rotor cores of the induction alternating current generator on vehicle. And a method for generating alternating current by an induction alternating current generator having plural claw poles of a pair of rotor cores engaging each other at a gap and first electromagnetic exciting means as a first exciter inside the rotor cores, includes the step of controlling magnetic flux permeating a stator core outside the rotor cores by controlling second electromagnetic exciting means mounted in the spaces of the above-mentioned gaps and generating magnetic field in the direction of repelling leak magnetic flux between the claw poles.
