An electromechanical machine having a stator and a rotor, the stator including at least one stator module of N toroid shaped electromagnets, the electromagnets arranged along an arc a predetermined distance apart defining a stator arc length. Each of the electromagnets has at least one gap. The rotor includes a disc adapted to pass through the at least one gap. The disc includes a plurality of permanent magnets spaced side by side about a periphery thereof and arranged so as to have alternating north-south polarities. The permanent magnets are sized and spaced such that within the stator arc length the ratio of permanent magnets to electromagnets is N+1 to N, where N is the number of electrical excitation phases applied to the electromagnets.

Axial flux permanent magnet machines

Brushless electromechanical machine

An electromotive machine having a stator element and a rotor element, the stator element including at least one set of N preferably 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 N to N+1, where N is the number of electrical excitation phases applied to the electromagnets. The electromagnetic members are energized to create high torque and smooth operation.

Brushless electro-mechanical device

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.
