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.

    一种示例系统,包括电动马达(102);与电动马达耦接的泵(104);液压回路(108),其流体耦接至泵并配置成从泵接收流体流;液压管线(110),其流体耦接至液压回路,其中液压回路被配置成将流体信号提供至液压管线,其中,流体信号指示液压回路的流体流需求;压力传感器(112),其安装至液压管线并配置成提供指示液压管线内的流体的压力级别的传感器信息;以及控制器(114),其配置成基于由传感器信息指示的压力级别控制电动马达的速度以改变由泵提供至液压回路的流体流率,从而满足流体流需求。
