Abstract

A single motor for servicing both an auxiliary circuit and a boost circuit of a regenerative hydraulic system. The hydraulic system includes at least one hydraulic pump that collectively or singly supplies hydraulic fluid to one or more hydraulic motors for an auxiliary function and to a fluid communication line selectively in fluid communication with a port of a hydraulic pump for boost, and a single auxiliary electric motor for driving the at least one hydraulic pump. By driving the two circuits independently using the single electric motor, overall cost of the hydraulic system is reduced and additional components such as another electric motor and inverter are eliminated.
