An electromotive machine having a stator element and a rotor element, the stator element including at least one set of four toroidally shaped electromagnetic members, the electromagnetic members arranged along an arc a predetermined distance apart defining a stator arc length. Each of the members has a slot, and the rotor element includes a disc adapted to pass through the slots. The disc contains a plurality of permanent magnet members spaced side by side about a periphery thereof and arranged so as to have alternating north-south polarities. These permanent magnet members are sized and spaced such that within the stator arc length the ratio of stator members to permanent magnet members is about four to six. Thc electromagnetic members are energized in a four phase push-pull fashion to create high torque and smooth operation.
