Product Description:

The MHD112B-058-NP1-BN is a servo motor built by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It converts drive current into controllable mechanical motion, allowing machine tools, packaging stations, and material-handling axes to position loads with feedback-regulated accuracy inside automated cells and other industrial equipment. Its 112-frame, B-length housing provides space for the liquid-cooling jacket without increasing the overall mounting footprint.

At stall, the rotor delivers a continuous output of 28.0 Nm, so medium-capacity actuators can remain energized without overheating. A housing rating of IP65 blocks dust and low-pressure water jets, while liquid cooling conducts heat away from the stator for stable thermal behavior. Position data comes from digital servo feedback (HSF), which uses an optical measuring method and relative detection to synchronize with the drive. The square flange measures 192 mm, matching standard motor interfaces. Power leads exit through a connector on side B, and a keyed shaft with a fitted shaft seal transmits torque while keeping contaminants out. An internal holding brake rated at 22.0 Nm engages automatically during power loss, and winding code 058 identifies the motor setup to the controller.

A centering pilot of 130 mm simplifies coaxial alignment between the motor and attached gear units. The unit operates in ambient temperatures from 0 to 40 °C and can be stored between -20 and +80 °C without degradation. The windings use Class F thermal protection, allowing hotspot temperatures up to 155 °C during cyclic overloads. Closed-loop positioning benefits from a system accuracy of ± 0.5 angular minutes, which helps improve contour-following quality on interpolated paths. Maximum installation altitude is 1000 m above sea level.
