An electrical machine assembly includes an armature assembly defining a rotational axis and a rectifier assembly including at least one diode and defining a central rectifier axis. The armature assembly is configured and adapted to be coupled with a rotor shaft for relative rotation therewith. The central rectifier axis is at a non-parallel angle relative to the rotational axis. A rectifier assembly includes a first diode and a second diode stacked with the first diode. The rectifier assembly includes an AC terminal positioned between the first diode and the second diode and a DC positive output pin electrically coupled to the first diode. A portion of the AC terminal extends outward from the rectifier assembly at a non-parallel angle relative to the central longitudinal axis of the rectifier assembly. A central longitudinal axis of the rectifier assembly can be parallel to the DC positive output pin.

A electromagnetic machine system includes a rotor and a stator positioned about the rotor. A current injection mechanism is coupled with windings of the stator and structured to inject electrical currents therein so as to change a flux distribution of a magnetic field produced by the stator. The injected currents may be harmonic currents. The rotor further includes an inductor positioned to interact with the magnetic field when the flux distribution is changed, to produce an electrical excitation current for exciting windings in the rotor. The machine system may be a synchronous motor or generator, and may be brushless. Applications of the current injection strategy to direct torque control and vector control are also disclosed.

A brushless, three phase wound field synchronous machine (WFSM) provides an electromechanical power transfer system wherein it may serve as both a starter and a generator. Power for the excitation system of the WFSM is provided by a three phase flux switching generator (FSG). The three phase FSG also provides position sensor functionality for the WFSM when the WFSM operates in the starter/motor mode.
