The Bosch R911290837 (MHD112B-048-NP1-AN) is an MHD series servo motor specifically constructed for industrial use. The unit, powered by a drive controller, includes an integrated 22 Nm holding brake and digital servo feedback. Built with a shaft complete with a key and sealing ring, it is encased in a surface-cooled housing allowing for natural thermal regulation. It operates at a rated speed of 2800 RPM, maxing out at 4500 RPM, offering a peak current output of 160 Amps and a maximum torque of 102 Nm. The separate feedback cable connects it back to the controller, transmitting feedback data. The brake works at 24 Volts DC, with a 25 millisecond connection time and a 50 millisecond disconnection time. The motor, weighting 34 kg in total, is fitted via four 14 mm holes on its flange, making it compatible with installations near operating machinery due to its IP65 protective casing. The handling of this motor and its related equipment requires trained personnel.
