The R911284987 (MHD112B-048-NG0-AN) model is a top-quality synchronous motor manufactured by Bosch Rexroth, known for industrial motion control devices. This unit is an element of a digital intelligent drive system and requires a specific drive controller for operations. Depending on the chosen cooling mode—natural or surface—the rated current varies between 6.9 to 16.9 A and 27.5 A, respectively. The motor generates a torque of 28/33 Nm (natural cooling) and 42 Nm (surface cooling) at a standstill, consuming 35.6 to 53.4 A of continuous current. Notable for its use in machine tools, robotics, and handling systems, this specific model does not feature a holding brake but does include a plain power output shaft which produces 2.7 to 11 kW when operating at 227 to 251 VAC. It is encased in housing safeguarded by IP65 protection, allowing durability in diverse weather conditions. Equipped with a digital servo feedback for position detection, the motor fits various mounting positions with its centering diameter of 130 mm.
