PURPOSE: To realize continuous rotation by providing means for imparting a magnetic trigger to a magnet part in response to a signal received from a position detecting means thereby making possible to rotate a rotor pair with a faint magnetic trigger. CONSTITUTION: Rotors 1a, 1b are provided, on the opposing faces thereof, with means 7 for imparting a magnetic trigger to a magnet part 4. The trigger means 7 is provided with means for detecting the magnetic trigger imparting position, i.e., a Hall element 11, closely to one rotor 1a. When the magnet part 4 of the rotor 1a passes through the Hall element 11, the Hall element 11 is actuated by the magnetic force therefrom to deliver a signal, for detecting the magnet part 4 of the rotor 1, to a drive circuit 9. When the respective magnet parts 4 face each other, the trigger means 7 is driven to impart a magnetic trigger. |
