<p>PURPOSE:To suppress an output generated in the armature winding of a stator by the magnetic flux of a permanent magnet in a generator comprising a rotor for feeding magnetic fluxes from a permanent magnetic, a field winding, and a stator having an armature winding and to easily suppress the generating output. CONSTITUTION:A generator is formed of rotors 1-3 secured to a rotary shaft 4 and a stator 5 provided on the outer periphery of the rotors. The rotor 1 is formed of pawl-like poles 12, 13 and a field winding 14 disposed at both sides and outer periphery of a cylindrical boss 11 secured to the outer periphery of the shaft 4. The rotors 2, 3 hold the same pawl-like poles 21, 22 and 31, 32 as the rotor 1 and disclike permanent magnets 23, 33 therebetween to be secured to a sleeve 6 of a nonmagnetic material. The stator 5 is formed with three-phase concentric stator windings 52 in a core 51, and has slots three times as many as the number of poles of the rotor 1. The current of the winding 14 is so controlled that magnetic fluxes of the magnets 23, 33 of the rotors 2, 3 flow in the same direction as or oppositely to the direction of the magnetic fluxes of the magnets 23, 33 of the rotors 2, 3 in response to the magnitude of a load.</p> |
