A slotless electric motor provides a ferromagnetic yoke that includes laminations of a ferromagnetic material interspersed with a high thermal conductivity nonferromagnetic material to greatly reduce the thermal resistance of this yoke. A thermally conductive coil form provides heat conduction paths on three sides of the coils to this yoke which may in turn attach to a heatsink providing fins that vary angularly along the axis and radius of the heatsink.

The present invention relates to a stator housing for an axial flux electrical machine, the stator housing being tubular and substantially cylindrical in shape, the inner surface of the housing comprising a plurality of recesses, each recess configured to receive an outer part of a conductive coil of a stator of an axial flux electrical machine. The cross-section of each recess, perpendicular to the axis of rotation of the axial flux electrical machine, is preferably elongate, the major dimension of each elongate recess extending substantially in the radial direction of the axial flux electrical machine.
