Product Description:
The MHD112A-035-PP0-BN servo motor is part of the MHD Synchronous Motors series from Bosch Rexroth Indramat. Designed for closed-loop positioning tasks, the motor turns electrical energy from an Indramat drive into precisely controlled rotation for conveyors, packaging stations, and handling axes. Frame size 112 and winding code 035 set its electromagnetic layout and match it to drives that can deliver the required current and voltage. This arrangement supports accurate speed and position control during repeated start-stop cycles.
The motor supplies a continuous standstill torque of 15.0 Nm, enabling stable force delivery when the shaft is held motionless under load. Protection to IP65 prevents dust ingress and water jets, while the stator jacket uses liquid cooling to remove heat so the rated output can be maintained without derating. It operates in ambient temperatures from 0 to 40 °C, and its 130 mm centering diameter aligns the flange precisely on machine frames. Digital servo feedback with an integrated encoder provides high-resolution speed and position data through an optical measurement method with low hysteresis. Class F insulation helps the windings tolerate elevated internal temperatures during operation. The PP0 variant is supplied without a holding brake, which reduces mass in applications that rely on drive-side dynamic braking.
The motor uses a keyed shaft for torque transfer, and the front face follows the DIN flange pattern with a diameter of 192 mm. The encoder provides absolute (>4096 revolutions) position detection and supports repeatability of ±0.5 angular minutes, enabling fine alignment in multi-axis assemblies. The power line exits through an output connector on side B, and a shaft seal is fitted to block contaminants. The side-B connector arrangement can simplify cable routing in installations with limited space near the mounting face. The unit may be stored between −20 and +80 °C and installed at elevations up to 1000 m above sea level. Its length code A keeps the overall depth minimal.
