Electro-hydraulic power unit with variable output flow
An example system includes an electric motor (102); a pump (104) coupled with the electric motor; a hydraulic circuit (108) fluidly coupled to the pump and configured to receive a fluid flow from the pump; a hydraulic line (110) fluidly coupled to the hydraulic circuit, where the hydraulic circuit is configured to provide a fluid signal to the hydraulic line, where the fluid signal is indicative of a fluid flow demand of the hydraulic circuit; a pressure sensor (112) mounted to the hydraulic line and configured to provide sensor information indicative of a pressure level of fluid within the hydraulic line; and a controller (114) configured to control a speed of the electric motor based on the pressure level indicated by the sensor information to vary a fluid flow rate provided by the pump to the hydraulic circuit to meet fluid flow requirements.
