ELECTRIC INDUCTION DRIVE ASSEMBLIES

摘要

A driving device was comprised of a rotor which had a circular-type core made of magnetic materials and a stator which has a circular-type core wound with coil radiating magnetic field in the direction to an axis of the rotator. There are conductive antimagnetic materials on the rotator to make an electrical repelling force compensating to the magnetic attractive force between a rotator and a stator. A stator had many electromagnet energized by the current flowing through the stator coil.
