Electrodynamic system comprising a variable reluctance machine

摘要: Stepping motor techniques are made viable for heavy duty machines with variable speed operation (motors or generators) by reason of the simplification and gain in specific output efficiency which results from constructions ensuring maximum saturation magnetic flux at stator pole faces minimal airgap between associated rotor faces. The density ferro-magnetic material forming arcuate poles may be varied (graded) circumferentially said relatively shaped arranged so as to render possible uni-directional current, 2-phase operation. Energy stored is minimised reduced energy inductively returned source vestigial coupled windings. Uni-directional currents only flow windings, switching circuitry, although not fundamentally novel, greatly simplified.
