1. A system for a generator set comprising:
an asynchronous electrical machine coupled to an engine;
an excitation capacitor selectively coupled to the asynchronous electrical machine by a capacitor switch device;
a power supply selectively coupled to the electrical machine by a power supply switch device; and
an electrical output coupled to the electrical machine by an output switch device,
wherein the electrical machine is structured to:
perform as a starter motor to start the engine when the capacitor switch device is open, the power supply switch device is closed, the output switch device is open, and the electrical machine mechanically drives the engine.
