The R911309333 (MHD071B-035-NG3-UN) is a synchronous servo motor manufactured by Bosch Rexroth. It is equipped with a low inertia rotor, four pole pairs, and designed for applications requiring precise speed and position control. Maximum rated speed is 5000 rpm, with a peak of 6000 rpm; theoretical maximum torque is 14 Nm, and continuous torque at standstill is 8.0 Nm. The unit features housing cooling via liquid cooling, insulation class F, and an IP65-rated case for protection against dust and water jets. It includes a holding brake with a torque of 10.0 Nm, a plain shaft with seal, and a digital servo feedback encoder (HSF) for relative position detection. Dimensional characteristics include a centering diameter of 95 mm, a flange size of 115 mm, and motor length code B, within the 071 size series. Power and feedback connectors are provided, and the power connection direction is adjustable within a 270-degree range. Installation is specified up to 1000 meters altitude, and the storage temperature range is -20°C to 80°C.
