1. A hydraulic pump drive assembly to supply hydraulic fluid for a work vehicle, the assembly comprising:
an electric machine configured to convert electrical energy from an electrical supply line to rotary motion;
a hydraulic pump configured to circulate the hydraulic fluid through a hydraulic supply line from the rotary motion of the electric machine;
a fixture having a first rotary machine interface configured to mount the electric machine to the fixture, a second rotary machine interface configured to mount the hydraulic pump to the fixture, and a work vehicle interface configured to mount the fixture to the work vehicle such that the hydraulic pump and the electric machine are fixed to the work vehicle through the fixture;
wherein the electric machine comprises an electric machine axial end and an electric machine mounting face disposed at the electric machine axial end, and wherein the first rotary machine interface contacts the electric machine only at the electric machine mounting face;
wherein the electric machine comprises a gearbox disposed at the electric machine axial end such that the electric machine mounting face is disposed at the gearbox of the electric machine; and
wherein the electric machine is operably coupled to the hydraulic pump such that energization of the electric supply lines causes the electric machine to drive the hydraulic pump.
