The Bosch Rexroth R911312861 (MHD093A-058-NG2-AA) is a synchronous servo motor designed for precision motion applications. It is equipped with a 32 Nm holding brake and operates with natural convection cooling, with an optional surface cooling configuration. The motor requires an AC 325–347 V input at 233 Hz and provides continuous output of 1.9-3.7 kW (natural cooling) or up to 5.9 kW (surface cooled), with a nominal torque range from 4.5 to 13.6 Nm. The standard output shaft features a sealing ring and a bearing configuration suited for high radial loads. It utilizes digital servo feedback with relative position detection, features a centering diameter of 130 mm, flange sizes of 140/150 mm, and a plain shaft with shaft seal. The motor is protected to IP65 and supports IMB5, IMV1, and IMV3 mounting positions, operating within an ambient temperature range of 0 to +40°C and achieving maximum speeds of up to 3500 rpm at rated currents of 3.4–10.3 A.
