Product Description:

Bosch Rexroth Indramat manufactures the MHD112C-035-NG3-BN as part of the MHD Synchronous Motors series. The unit is a servo motor built to drive axes that require controlled torque, velocity, and position in industrial automation cells, packaging lines, and material-handling stages. With its plain shaft and integrated holding brake, the motor interfaces directly with gearboxes or couplings while keeping mechanical play low. Its optical measurement method and relative position detection feed high-speed drives with rotor data for closed-loop current and velocity control.

At standstill, the motor can exert 38.0 Nm of continuous torque, allowing reliable force delivery for heavy tables or gantries without overheating. The housing complies with IP65, so dust ingress and water jets do not compromise the internal windings. A 130 mm centering diameter aligns the stator accurately on the machine frame, which helps limit radial runout and supports alignment with planetary gearheads used in multi-axis assemblies. Heat generated in the windings is removed through liquid cooling, which stabilizes temperature during high duty cycles. The motor uses a 192 mm square flange for mechanical attachment, matching the ISO bolt pattern for size-112 servomotors.

Dynamic stopping power comes from a holding brake rated at 70.0 Nm, allowing the axis to stay locked during power loss or vertical loading. Position feedback is handled by digital servo feedback (HSF), delivering high-resolution incremental data that the drive interprets as relative rotor position. Combined with an overall system accuracy of ± 0.5 angular minutes, the motor maintains precise repeatability during indexing tasks. Continuous operation is permitted in ambient air from 0 to 40 °C, and the design supports installation up to 1000 m above mean sea level without derating.
