Summary:

AbstractThis document presents and discusses the design, development, and demonstration of a 3,000 to 8,000 psi (207 to 552 bar) electronically controlled, overcenter, variable-displacement hydraulic motor (VDHM) in which output speed and position control are effected solely through wobbler position control. This approach contrasts with traditional systems that are normally controlled through a large servovalve which throttles flow across the motor control portraits By connecting the variable-displacement hydraulic motor (VDHM) motor directly to supply and return and controlling through wobbler modulation, the need for a large throttling servovalve with its associated flow losses is eliminated. This can result in significant improvement in peak flow consumption, overall efficiency, and package size
