Product Description:
The MHD112B-035-NP1-BN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It converts electrical energy into controlled rotary motion for positioning or speed-regulated tasks in automated machinery, making it a common choice for packaging lines, material-handling axes, and tooling spindles where closed-loop control is required. Its synchronous motor design supports repeatable acceleration and stable speed control on axes that must respond accurately to drive commands. Additional features include a keyed shaft with a shaft seal, a power connector on side B, liquid coolant passages molded into the housing, a maximum installation altitude of 1000 m above mean sea level, motor length code B, size 112 laminations, and winding code 035 for its electrical characteristics.
This model delivers a continuous standstill torque of 28.0 Nm, allowing stable load support when the shaft is energized but not rotating. An enclosure rating of IP65 keeps dust and low-pressure water jets out, so the motor can be mounted near process equipment without separate protective housings. Position data are returned through digital servo feedback (HSF), giving high-speed controllers fine resolution for velocity and position loops during operation. The motor uses a 192 mm square flange, and alignment is aided by a 130 mm centering diameter that matches standard machine frames. Heat generated in the stator windings is removed by liquid cooling, which maintains winding temperatures below their thermal limits even at high duty cycles and helps the Class F insulation tolerate internal hot spots up to 155 °C.
A factory-mounted brake supplies 22.0 Nm of holding torque to secure vertical loads whenever drive power is removed. The windings carry Class F insulation, matching the 0 to 40 °C operating range and the -20 to +80 °C storage window. System accuracy is held within ± 0.5 angular minutes thanks to optical measurement of rotor position and the relative detection format. The relative feedback format allows the drive to monitor rotor movement continuously during commanded motion.
