<p><P>PROBLEM TO BE SOLVED: To provide a generator capable of obtaining a stable power generation force in a low-speed rotation and a high-speed rotation thereof in generating power using a drive torque of wind power and water power. <P>SOLUTION: A stator coil is configured by a coreless winding to suppress an action of a cogging torque in a low-speed rotation and is connected to a three-phase output terminal via a first switching means so that the inductance of the winding can be switched to be large or small, and a second switching means for short-circuiting the output of a plurality of coreless windings is provided on the three-phase output terminal. A control means for detecting the number of rotations of a driving rotating shaft exerts control so that the inductance of the coreless winding can be increased by the first switching means in an excessively small rotation (low-speed rotation) of the rotating shaft and an electric brake can act on a magnet rotor by the second switching means in an excessive large rotation of the driving rotating shaft. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
