The Bosch Rexroth R911280027 (MHD093B-058-NP0-AN) is a 4-pole synchronous servo motor engineered for high-torque applications such as machine tools, robotics, and printing equipment. This MHD093B unit delivers continuous torque from 5.4 to 8.1 Nm with natural convection cooling and up to 24.7 Nm when equipped with liquid cooling, requiring a coolant flow of 1.3 l/min for heat dissipation of 900 W. The device operates on AC supply voltage between 200 and 347 V with a power range of 1.7–12.7 kW. Standstill current consumption ranges from 22.5 to 26 A for natural convection and reaches 42.8 A for liquid cooling, with correlated standstill torque values of 17.5–20 Nm and 33.3 Nm, respectively. Key features include a digital servo feedback encoder (HSF), keyed shaft design with shaft seal, output connector for power, centering diameter of 130 mm, flange size of 140/150 mm, and support for IMV1, IMV3, and IMB5 mounting configurations. The motor is specified for continuous operation at ambient temperatures from 0 to 40°C and installation altitudes up to 1000 meters. No holding brake is included.
