Product Description:
The MHD112B-058-PP1-BN is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. As a rotary drive element, it couples an absolute multi-turn position system with digital servo feedback, allowing closed-loop control in automated tooling, packaging, and material-handling axes. Its internal encoder and keyed output shaft provide position reference and torque transmission for machinery that needs precise electromechanical motion.
The motor delivers a continuous standstill torque of 28.0 Nm, and its integrated holding brake supplies 22.0 Nm to lock the load when power is removed. A flange diameter of 192 mm and a centering pilot of 130 mm align the size 112, length B frame to gearboxes or adapter plates. Mechanical coupling is by a keyed shaft that is sealed against contamination, and the power leads exit toward side B through an output connector. Optical measurement is used for positional feedback, and the absolute multi-turn system tracks more than 4096 revolutions. The winding code 058 indicates the electrical characteristics required from the drive. Digital servo feedback with an integrated encoder supports bidirectional counting and velocity data. Motor construction includes insulation class F windings, and the housing is prepared for liquid cooling circuits. The motor can be installed at heights up to 1000 m above mean sea level.
The housing employs liquid cooling to remove losses, enabling full torque output within an operating range of 0 to 40 °C. The motor has a protection level of IP65, and a shaft seal is fitted to maintain that rating. Class F insulation permits winding temperatures suited to continuous industrial duty, and the system accuracy is held within ± 0.5 angular minutes for repeatable positioning. Storage temperatures from -20 °C to +80 °C protect materials during shipping or downtime.
