Abstract:
A paving machine having electric powered systems in lieu of hydraulic systems for performing work at a work site may include an integrated generator operatively connected to a power source of the paving machine, such as an engine, to produce AC power. A power converter may receive the AC power and output DC power to electric motors, with each electric motor being operatively connected to a corresponding one of a plurality of mechanical components. The power converter may distribute power from the generator to the plurality of electric motors in response to commands to actuate the plurality of mechanical components input at an operator station. The electric powered systems may include propulsion devices, material conveyors, augers and the like.
