The radial piston design ensures very high starting torque efficiencies, especially at high pressures where they are most required in mobile applications. Efficiency is typically > 94% at 400 bar.
The maximum torque requirement for wheel motor applications generally occurs with the vehicle al standstill or at low speeds, for example, during acceleration from stand-still or when overcoming an obstacle or slope.
High starting torque in the hydraulic motors therefore means better vehicle performance, less energy wastage and heat generation, especially with frequent stop-start work cycles.
