Abstract

A hydraulic axial piston pump driven by an electric motor, comprising an outer casing (11) that is formed monolithically with elements (25) for fixing the casing to the stator assembly (26) of the electric motor (23); the electric motor (23) being thus coupled directly to the outer casing (11).
