Abstract
A low inertia, speed variable induction motor with a stator, a yoke, and a rotor mounted on an output shaft being accommodated in the interior of a frame, wherein the stator is fixedly provided inside the frame, the yoke is rotatably mounted inside the frame in a manner to oppose the stator with a small gap between them, and a cup-shaped rotor is inserted into the small gap between the yoke and the stator, thereby reducing the size and weight of the driving body including the cup-shaped rotor, and improving its high speed response property.
