Abstract:

A torque delivering apparatus, including: polygonal cross-section stator body having a plurality of exterior side faces of even number extending between opposite axial end faces, the stator including cylindrical bore extending between the opposite axial ends and centred on central axis of the stator body; a rotor assembly having cylindrical cross-section sized for rotation within the cylindrical bore about the central axis with at least one permanent magnet and shaft coupled to the magnet for rotation; and a plurality of solenoid coils, each coil having plurality of windings and routed to have sections extending parallel along opposite ones of the plurality of exterior side faces; wherein each of the plurality of coils is configured to selectively receive current and generate magnetic field in the stator that is applied to the rotor magnet, the rotor being subject to magnetic torque within the cylindrical bore for rotating and aligning the magnetic field of the permanent magnet with the generated magnetic field.
