Abstract

PURPOSE: To improve high speed responsibility by providing stators and rotors rotating within the respective stators on the inner and outer sides of an exciting coil and providing the rotors with radially spaced projections and the stators with attractive projections corresponding to these projections.
CONSTITUTION: Rotors 12 and 13 and associated stators 14 and 18 are provided respectively on the outer and inner sides of an exciting coil 17. The rotor are provided with radially spaced projections 12a and 13a, and the stators are provided with attractive projections 14a and 18a corresponding to these projections. With the provision of such projections on the rotors and stators the moment of inertia can be reduced without reducing the output, so that it is possible to extremely improve the high speed response characteristic. In addition, it is possible to reduce the impact force at the time of stopping the operation, thus permitting elimination of noise and vibrations.
