A radial-air-gap induction motor is constituted so as to have two air gaps by setting a rotor between a cylindrical outer stator and inner stator in order to improve an efficiency by increasing the ratio of torque/(square of current) by a two air gaps, apply windings for generating a rotating magnetic field to the outer and inner stators, and form squirrel-cage windings on the rotor.

Induction motor

In an axial-air-gap induction motor which has a disk-shaped stator and rotor placed coaxially around a rotating shaft with their surfaces opposing each other across a predetermined gap, the stator and rotor are each composed of a disk-shaped yoke and teeth fitted and secured in the yoke, making it easy to fasten the stator to the bracket, and the rotor to the rotating shaft, as well as to mount windings in the stator core and rotor core.
