The Bosch Rexroth MPN R911320786 (MHD112B-058-NG0-RN) is a synchronous servo motor engineered for industrial environments. It features a 192 mm flange, 130 mm centering diameter, and plain shaft with an integrated shaft seal. The unit operates with liquid-cooled housing and employs digital servo feedback (HSF) for relative position detection. The motor delivers a continuous standstill torque of 28.0 Nm, has a motor length B, and winding code 058. With four pole pairs, special magnet materials result in low inertia. The power connection is directed to the right via power connector. It is rated IP65 and specified for installation heights up to 1,000 m with protection against fluid accumulation around the vertical shaft. The motor is supplied without a holding brake.
