Patent ID: 11870301

Abstract:
A radial flux electrical machine is disclosed. The machine comprises a body of the stator having a body that defines a longitudinal axis a substantially cylindrical inner surface and an inner volume, and having a plurality of electromagnetic elements, each of which includes a stator core of ferromagnetic material and a winding of electrically conductive material located around at least part of the stator core of the electromagnetic element, the electromagnetic elements being arranged around the inner surface of the stator, and operable to induce a magnetic flux field in a radial direction in the inner volume of the stator, and a rotor located within the inner volume of the stator, and rotatable with respect to the stator. The inner surface of the body of the stator and the electromagnetic elements of the stator define cooperating engagement features of shape that serve to prevent relative rotation between the body of the stator and the electro-magnetic elements, and which allow relative longitudinal movement between the body of the stator and the electromagnetic elements.
