A stator coil winding arrangement comprises an inner layer and an outer layer, which define the two layers of the coil. A first turn of the inner layer is positioned directly over the outer layer. All subsequent turns of the inner layer return to the inner layer to be positioned over the inner layer

A stator coil winding arrangement comprises an inner layer and an outer layer, which define the two layers of the coil. A first turn of the inner layer is positioned directly over the outer layer. All subsequent turns of the inner layer return to the inner layer to be positioned over the inner layer. With this winding arrangement, total losses in the stator coil are reduced by approximately a factor of two.
