Abstract
A variable reluctance electric motor system including a variable reluctance motor having main windings (A,B,C,D) and auxiliary windings closely coupled to the main windings, a main storage battery for driving the motor terminals (10,11) (that will be referred to as DC supply terminals), and a power converter circuit (FIG. 2) for charging the battery from the DC supply, in which the motor is included in the power converter circuit to function as an isolating transformer to isolate the battery from the supply when on charge.
