Product Description:

Bosch Rexroth Indramat manufactures the MHP112D-027-HG3-BNNNNN for the MHP Synchronous Motors series. This synchronous servo motor is built in size 112 with length code D and is used in industrial automation where precise speed and position control are required. A plain shaft with a sealing ring transfers output to couplings, pulleys, or gear stages while helping protect the bearing area from contaminants. An incremental encoder with 2048 lines supplies position data to the drive controller, allowing accurate closed-loop regulation on conveyors, material-handling axes, and packaging machinery. This feedback arrangement supports stable motion control during indexing, speed regulation, and repeated positioning cycles in automated equipment.

Under natural convection, the motor provides 48.0 to 57.0 Nm of standstill torque up to a characteristic speed of 2000 rpm, and it can draw 99.9 A during acceleration to meet short-term load demands. A torque constant of 2.51 Nm/A relates phase current to developed torque, so the current loop can produce predictable output across the operating range. Winding inductance is 5.7 mH, and the winding resistance is 0.35 ohm, which affects current rise and copper loss in the stator. These electrical values are important for matching the motor to a compatible servo drive and tuning response during changing load conditions. Insulation class F supports the thermal limit during normal operation.

An integrated brake supplies 70.0 Nm of static holding torque, and its 24 V DC magnet coil draws 1.29 A so vertical loads remain secure when the drive is de-energized. The housing is rated IP65 and is approved for operation from 0 to +40 °C without forced airflow because heat is dissipated through the motor surface. Mechanical dimensions include a 130 mm pilot diameter and a total length of 526 mm, while power cabling connects on side B. After brake release, the rotor may accelerate to 3000 rpm, and the voltage constant is 154.5 V/1000 rpm. The brake supports load holding at standstill, while the higher running speed is available during powered motion.
