PURPOSE:To obtain rotational power of two sets or more with a device of small size and light weight, by a method wherein two rotors or more are constituted independently within the same shaft. CONSTITUTION:A center shaft is projected at side of upper and lower surfaces, and one flat motor is arranged to each of both portions. As the motor therefor, a brushless motor to rotate and drive each of rotor magnets 18, 18' by control power supply to each of stator coils 21, 21' is used. Respective motors have rotary bodies 4, 4', rotor magnets 18, 18', stator coils 21, 21', rotary yokes 22, 22', wiring circuit boards 25, 25', sensors 40, 40', and signal of the sensors 40, 40', FG signal and the like are inputted to an electronic circuit connected at outside and control power supply is performed to each of the stator coils 21, 21', whereby rotational drive power is generated independently to each of the rotor magnets 18, 18'. |
