ELECTRICAL POWERING SYSTEM COMPRISING AN ASYNCHRONOUS MACHINE AND PROPULSION ENGINE PROVIDED WITH SUCH AN ELECTRICAL POWERING SYSTEM

摘要

The invention provides a system for supplying electrical energy, comprising an asynchronous machine (100), an arrangement (130) for driving a rotor (110) of the asynchronous machine in rotation by a rotor of a motor. of propulsion and an electrical connection (140) for the supply of at least one electrical equipment by said rotor of the asynchronous machine, characterized in that the asynchronous machine (100) being moreover equipped to receive alternative electric energy by a stator (120) of said asynchronous machine, it has, over a predetermined range of speed of drive by said rotor of the propulsion motor of the rotor of the asynchronous machine, an electrical energy transfer efficiency of said stator (120) said rotor (110) privileged with respect to the efficiency of conversion of mechanical energy of rotation into electrical energy.
