Title
Sizing Considerations for Electrohydrostatic Pumps and Motors
Scope
Recommendations for EHA Pump sizing based on considerations for various actuator performance requirements, including no-load speed, breakout torque, low temperature, stiffness, dynamic response, maximum pressure-velocity capability, and other conditions.
Rationale
EHA Pump sizing criteria are fundamentally different than those published for main-engine hydraulic pumps and hydraulic motors. EHA pump displacements have a number of different corner sizing parameters related to actuator performance requirements.
