Patent ID: 8836196

Claim:
A method for reducing losses in an electrical machine, the method comprising: forming a first stator portion from a first lamination stack and a second lamination stack, the first lamination stack and the second lamination stack having a gap therebetween, the first lamination stack and the second lamination stack being arranged circumferentially with respect to a rotational axis for the electrical machine; forming a second stator portion from a third lamination stack and a fourth lamination stack, the third lamination stack and the fourth lamination stack having a gap therebetween, the third lamination stack and the fourth lamination stack being arranged circumferentially with respect to the rotational axis for the electrical machine; and coupling the first stator portion to the second stator portion by at least one back return lamination to provide a flux path at least partially around a coil arranged circumferentially with respect to and fully encircling the rotational axis, wherein the first stator portion is positioned on a first side of the coil, and the second stator portion is positioned on a second side of the coil; wherein the electrical machine is at least one of a transverse flux machine or a commutated flux machine.
