Abstract: An electrical machine includes a rotor with a rotational axis, a coil arranged circumferentially with respect to and fully encircling the rotational axis, and a stator assembly. The stator assembly includes first and second lamination stacks comprising associated pluralities of laminae, the stacks being arranged circumferentially with respect to the rotational axis on opposing sides of the coil for conducting magnetic flux. The stacks are configured with gaps generally radially through the laminae thereof, defining separate circumferential segments in each laminae, to prevent creating a continuous electrical circuit around the rotational axis in the segments. Each laminae has a connecting ring spaced radially from the segments, and beams connecting the segments to the ring as a unitary piece. Back return elements extend axially between the stacks to provide a flux path therebetween, and are positioned circumferentially between adjacent parts of the beams and radially between the segments and the ring.
