1. A system for starting an engine comprising:
a regulated power source having a housing, a synchronous machine and a flywheel sharing a common shaft in the housing; said synchronous machine comprising:
an excitation stator winding;
an excitation rotor winding cooperative with said excitation stator winding, said excitation rotor winding rotating with a rotation of the common shaft of said regulated power source;
a main stator winding;
a main rotor winding cooperative with said main stator winding, said main rotor winding affixed to said common shaft and rotatable with the rotation of the common shaft of said regulated power source; and
a squirrel cage winding cooperative with said main stator winding and said main rotor winding, said squirrel cage winding being rotatable with the rotation of the common shaft of said regulated power source;
an electrical generator having a shaft therein;
the engine having a main shaft integral with or coupled to said shaft of said electrical generator;
a mains power supply; and
a switch cooperative with said electrical generator and said mains power supply and the synchronous machine of said regulated power source, said switch selectively making an electrical connection between said synchronous machine and said mains power supply, said switch adapted to transfer electric power from the synchronous machine of said regulated power source to said electrical generator so as to cause said electrical generator to rotate the shaft thereof in order to rotate the main shaft of said engine during startup of said engine.
