The Bosch Rexroth MPN R911283437 (MHD112B-048-NP1-BN) is a synchronous servo motor equipped with a B-side power output connector and a keyed shaft in accordance with DIN 6885-1, featuring a shaft seal. Designed with insulation class F per DIN VDE 0530, it operates at a rated speed of 2800 min-1 (187 Hz) with a voltage constant of 80 V per 1000 min-1. The unit has a holding brake rated at 22.0 Nm, integrates liquid cooling, and utilizes digital servo feedback for position detection. Its mechanical dimensions include a flange size of 192 mm, centering diameter of 130 mm, and a length code 'B'. The motor's low inertia is attributable to its specific magnet material choice, and a brushless configuration minimizes heat dissipation. Installation should ensure correct shaft alignment and secure power supply connection. The integrated brake is managed directly by the drive controller.
