Product Description:

The MHD112B-035-PP2-BN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Designed for machine tools, packaging stations, and material-handling modules, it converts drive-bus power into tightly regulated rotary motion that remains synchronized with the controller command profile. An integrated optical encoder supplies digital servo feedback, allowing the control loop to monitor rotor angle and speed without external sensors. The motor has a keyed shaft for secure torque transmission to couplings or pulleys.

The centering pilot is 130 mm, and the square flange measures 192 mm, so the housing mates with common gearbox and frame geometries. A continuous standstill torque of 28.0 Nm is available for static load holding without overheating. The stator windings use insulation class F, which allows winding temperatures up to 155 °C before degradation. Environmental sealing corresponds to IP65, protecting internal components from dust ingress and water jets. Storage is permissible between -20 to +80 °C, while operation must stay within 0 to 40 °C and below a setup elevation of 1000 m above mean sea level. Power leads exit toward side B through an output connector that simplifies cabinet wiring.

Thermal management relies on liquid cooling channels that circulate coolant through the stator jacket. A holding brake rated at 32.0 Nm secures the shaft when power is off, which supports vertical axes. Motion precision is supported by the optical measurement method, which attains a system accuracy of ± 0.5 angular minutes. The encoder provides absolute position over more than 4096 revolutions, so homing is not required after power loss. A shaft seal keeps coolant and contamination away from the keyed output shaft, and the B-length frame with winding code 035 matches the 112 size envelope.
