  • Publication number: 20120153884
    Abstract: A controller for managing electrical power storage in a machine having an electric energy storage device and an electric motor comprises a gate drive stage for providing gate signals to one or more power electronics elements, as well as a control processor adapted to generate gate signals and supply the generated gate signals to the gate drive stage for controlling the one or more power electronics elements. The gate signals control the one or more power electronics elements to power the motor windings in a drive mode of operation and to charge the electric energy storage device in a charging mode of operation. In either mode, the motor windings are used as conductors or inductive elements.

  • Publication number: 20060144634
    Abstract: In order to enhance an operator's ability to control a work machine, an operator control station includes a seat assembly that is moveably mounted to a body of the work machine. The operator can control, at least in part, primary operator controllable aspects of the work machine by manipulating work machine operating controls attached to move with the seat assembly. The operator can monitor a work machine operating condition, at least in part, via a work machine operating condition display panel also attached to move with the seat assembly. In addition, the operator control station is interchangeable among a plurality of work machines of different types and sizes.
