Abstract
An example system includes an electric motor (); a pump () coupled to the electric motor; a hydraulic circuit () fluidly-coupled to the pump and configured to receive fluid flow from the pump; a hydraulic line () fluidly-coupled to the hydraulic circuit, wherein the hydraulic circuit is configured to provide a fluid signal to the hydraulic line, wherein the fluid signal is indicative of a fluid flow demand of the hydraulic circuit; a pressure sensor () mounted to the hydraulic line and configured to provide sensor information indicative of pressure level of fluid in the hydraulic line; and a controller () configured to control a speed of the electric motor to vary fluid flow rate provided by the pump to the hydraulic circuit to meet the fluid flow demand based on the pressure level indicated by the sensor information.
