Abstract

A variable reluctance motor includes a phase assembly (102, 801) having more than one phase unit (121, 122, 123, 821, 822, 823), each of said phase units comprising at least one module (131, 132, 831, 832), each said module comprising an electrically conductive coil (140, 840) wound around the module in one or more windings, each of said phase units being magnetically isolated from every other phase unit, each of said phase units defining a flux path. The motor further includes a ferromagnetic core (101, 810) within the flux path.
