PROBLEM TO BE SOLVED: To provide a flux controller for controlling flux flowing through a stator by increasing and decreasing a magnetic path air gap in response to a rotational speed by means of a simple mechanical unit, and generating a predetermined constant voltage at all times by controlling flux flowing through the stator during high speed operation. SOLUTION: A winding 14 of a stator 4 is composed of a three-phase output winding 18 and a three-phase flux control winding 19 of reverse winding at a comb 10 wherein the flux control winding 19 is connected with the output winding 18 through a flux control switch 24. A predetermined constant voltage is generated by performing the on/off-control of the flux control switch 24 and the magnetic path air gap control of a flux control ring 7 in response to the number of revolutions of a rotor and a load.
