ABSTRACT:
A low inertia induction motor to increase to speed responding characteristic at the time of its start and stop comprises a stator core fixed inside a frame, a yoke disposed in confrontation to the stator core with a space gap and a rotor interposed within the space gap between the yoke and the stator core. A through-hole is formed at the center portion of the frame for supporting the yoke or the stator core, a rotationary shaft is rotatably inserted into the through-hole and the rotational shaft is attached with a rotational plate for supporting the rotor and a cooling fan for feeding cooling air in the interior of the frame.
