Summary:PROBLEM TO BE SOLVED: To provide a small generator that can generate electric power with small rotating torque, by suppressing the influence of cogging torque acting on the rotation of a rotor. SOLUTION: Rotor magnetic poles formed by conducting field coils 3 of the rotor 1 starts conduction at an intermediate position of adjacent magnetic substance blocks 5. The rotor magnetic poles rotates the rotor 1, by alternately repeating the operations of conduction and interruption to the field coils 3, so as to interrupt the power supply at the positions facing the blocks 5. Inductive power, induced by the magnetic flux change of a magnetic circuit formed by a yoke 6, is extracted from an output coil 7. COPYRIGHT: (C)2007,JPO&INPIT
