A rotating rectifier module for rectifying a multiphase alternating current signal provided by a multiphase alternating current power supply includes a housing, a circuit board, a plurality of input terminals, a first output terminal, a second output terminal, and a plurality of rectifier circuits. The housing has an outer surface, an inner surface defining a central opening for receipt of a rotatable shaft, and at least one cavity located between the outer and inner surfaces. The circuit board is mounted in a plane substantially normal to the outer surface. The input terminals are located on the circuit board. Each input terminal provides for electrical connection to one phase of the power supply. The first and second output terminals are located on the circuit board for electrical connection to a direct current load. The rectifier circuits are electrically connected in parallel between the first and second output terminals. Each rectifier circuit is mounted inside one of the at least one cavity on an outermost surface that defines the cavity and is electrically connected to one of the input terminals.

An electric motor or generator assembly includes a component, such as a stator, having a plurality of windings. A wire set including a plurality of individually conductive wires twisted together is manipulated within a core to establish the desired number of windings having the desired cross sectional area. In one example, a plurality of such wire sets are manipulated simultaneously to establish the windings. Litz wire is one example type of wire set that is useful in an assembly designed according to this invention. There are more than 100 individual wires within each winding according to one example stator designed according to this invention.
