Patent ID: 7148596

Claim:
A magnetic rotating motor generator comprising: a rotating portion having a shaft on which it turns, with disks extending from the shaft, said shaft and disks being made of a non-magnetic substance, and the periphery of the disks is provided with a group of permanent magnets tilted at a predetermined angle in an embedded manner; a group of electromagnets that are disposed adjacently to the rotating portion so as to oppose the group of permanent magnets; a positional sensor for detecting rotational positions of the group of permanent magnets; a controller for applying an electric current to the electromagnet on the basis of a detected signal from the positional sensor; and a power generating section for obtaining power from a coil of the electromagnet, wherein a rotation mode and a power generation mode are alternated when the controller periodically applies the electric current to the electromagnet, so that power generation is performed while a function as a motor is exhibited.
