Abstract
A stator includes a cylindrical core with a plurality of longitudinally extending slots, a first winding set formed as a first cascaded wire in two radial layers of the slots, a second winding set formed as a second cascaded wire in two other radial layers of the slots, and a jumper connecting the first and second wires. A first winding set may have three cascaded phase wires in first and second layers of the slots, and a second winding set may have three cascaded phase wires in third and fourth layers of the slots. A winding set of a first phase may have a first cascaded wire in two radial layers of a first one of the slots, and a winding set of a second phase may have a second cascaded wire in two other radial layers of the first one of the slots.
