Short circuit rotors for induction transmission and asynchronous three-phase motors using epicyclic gears has switch or short circuited windings on core

摘要

The rotor is driven by mechanical force and short circuit windings of a second section. Alternatively permanent magnets can be used or a cage rotor of and the short circuited windings of the first section. Another version may include a switch or short circuited windings in a core.
