Abstract

PURPOSE: To increase or reduce a varying speed according to the characteristic of a load and vary a speed smoothly or stop a device, by moving one of two stators rotationally and concentrically with a rotor, and by regulating the rotational speed.
CONSTITUTION: A first stator 24 and a second stator 25 with windings 22, 23 applied to an external side section confronted with rotor cores 2, 3 are arranged in parallel with a mechanical frame 14. Between the mechanical frame 14 and the first stator 24, a slip bearing 26 is set, and the slip bearing 26 is fixed with a stop ring 28 fitted on the mechanical frame 14. The second stator 25 is fixed on the mechanical frame 14 with a fixing ring 27. The first stator 24 is moved rotationally and concentrically with a rotor 7 by the working of a miniature motor 30. Then, a voltage phase shifter is constituted by the rotational movement of the first stator 24, and the second stator 25.
