摘要： A permanent magnet generator incorporated in a diskette that can be inserted into a floppy disk drive is disclosed. In the permanent magnet generator, electric power is generated as a rotor is caused to rotate at a revolution twice to ten times as high as that of the drive shaft of a floppy disk drive by transmitting the rotation of the drive shaft to a rotor via a speed increasing mechanism incorporated in a diskette. Since the cogging torque of the generator is reduced, the rotor can be caused to rotate with a small drive torque. This allows the generator to produce a high output.
摘要翻译：公开了一种结合在可插入软盘驱动器的软盘中的永久磁铁发生器。在永久磁铁发电机中，当通过将驱动轴的旋转传递给转子时，通过将驱动轴的旋转传递到转子而使转子旋转的速度是软盘驱动器的驱动轴的两倍至十倍的旋转，产生电力结合在磁盘中的增速机制。由于发电机的齿槽转矩减小，所以能够以小的驱动转矩使转子旋转。这允许发电机产生高输出。

The rotor comprises an anisotropic bond magnet section and a soft magnetic section wherein the anisotropic bond magnet section is preformed in magnetic field and then formed to be integrated with the soft magnetic section in nonmagnetic field. Subsequently, it is heat hardened to produce a surface magnet type rotor. Magnet units, each having a magnetic pole composed by bonding a pair of permanent magnets such that the directions of magnetization become symmetric with respect to the bonding surface, are linked such that magnetic poles of different polarities appear alternately on the magnetic action surface thus forming an anisotropic magnet body.
