摘要： An electric motor driven pump assembly configuration that includes an electric motor, a hydraulic pump driven by the electric motor is provided. The hydraulic pump is driven by the electric motor to convert electrical power into hydraulic power. A multi-inlet hydraulic pump enhances cooling flow through a pump case of the assembly and also enhances cooling flow for cooling the electric motor and corresponding drive/control components.
