The R911317142 (MHD115C-035-NG1-AN) is a Bosch Rexroth synchronous servo motor engineered for dynamic motion control applications. It weighs 55.8 kg and employs a digital servo feedback (HSF) encoder for relative position detection. The motor has a torque constant of 1.31 Nm/A, winding resistance of 0.12 ohms, and supports a maximum speed of 4500 rpm, with theoretical torque output of 231 Nm. Rated at 4.3 kW (natural cooling, 60 K), it delivers 35.6 Nm at 67 Hz. Under liquid cooling (60–100 K), the rated power increases, sustaining 133 Nm at 2000 rpm. It includes a holding brake with 70 Nm torque, has a plain shaft with a sealing system, housing for liquid cooling, and side A output connector. The unit features a centering diameter of 180 mm, flange size 192 mm, and operates optimally within 0 to +40°C, with transport permissible from -20 to +80°C.
