PURPOSE: To obtain a high torque output with a low speed without using the high revolution member of an electric motor, by a method wherein a deceleration mechanism is formed on a part where the stator and rotor of the motor are unified. CONSTITUTION: Two stator rings 20a and 20b which move on a track without rotation are provided with 180 degrees difference between each other around a rotor 145 having a predetermined number of lobes 16. Each ring has rollers 22 more than the lobes 16 by one. That is, in the case of a system with 12 rollers, the reduction gear ratio is 1:11. Windings 36a-36h are so provided as to face each other as poles. The stator ring moves as a magnetic force, i.e., an electric impulse, induced by the winding is successively moved around the facing poles. As a result, the rotor rotates at a speed which is obtained by dividing the speed of the stator ring by the built-in reduction gear ratio. As the two stator rings are respectively moved on the tracks shifted from each other by 180 degrees, the mass on the track and the torque of the rotor can be balanced. |
