ABSTRACT:
In an electric motor having a stator with phase windings selectively energized to produce a progressively moving electromagnetic field and a magnetized rotor which seeks a minimum reluctance position within that field, energy withdrawn from a phase winding after de-energization so as to collapse the field produced by that winding passes from one end of the winding through a first connection to a capacitor where it is stored and re-applied through an alternative connection to the other end of the winding when it is next energized whereby to provide fast rise and fall of current in the winding without restricting the current which can intermediately be drawn by the winding from a principal power supply.
