Product Overview

The Rexroth A6VM250EP6D1P001H/71MWV0S4A29WV-0 (material number R902288015) is a high-performance axial piston variable displacement motor from the Bosch Rexroth A6VM series, engineered for closed-loop and open-loop hydrostatic drive systems. Utilizing a bent-axis rotary group design, this motor converts hydraulic pressure into mechanical rotary torque with variable displacement capability, allowing infinitely adjustable output speed and torque to match dynamic load requirements. The A6VM250 frame size delivers a nominal displacement of 250 cm³/rev and is configured with the EP control variant, providing electro-proportional displacement control for precise, remote, and automated speed regulation. This motor is a direct-fit, OEM-equivalent component suited for demanding mobile and industrial drive applications where high power density, wide speed range, and reliable starting torque under load are essential.
