Abstract
A generator to generate electrical power from rotational motion and a method of making the generator. The generator includes a rotor including a plurality of magnetic poles; and a stator including a magnetic core comprising a body and teeth extending radially from the body and defining a plurality of slots therebetween. The stator also includes a first three-phase winding and a second three-phase winding, each of the first three-phase winding and the second three phase winding including first, second, and third phase windings comprised of coils individually wound around each of the teeth. At least two coils of each of the first, second, and third phase windings of the first three-phase winding and the second three phase winding are individually wound on teeth positioned next to each other.
