Product Description:

The MHD112B-035-NP2-BN servo motor is built by Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. It converts drive commands into controlled rotary motion for positioning, indexing, or continuous-transport axes inside automated machinery. By combining high torque density with closed-loop feedback, the unit supports precise, repeatable movement on packaging lines, material-handling gantries, and similar systems. Its design also suits servo applications that require accurate speed control and consistent stopping positions. This makes it suitable for machines that switch frequently between acceleration, dwell, and deceleration.

It delivers a continuous standstill torque of 28.0 Nm, allowing stable holding force without excess heat. Position feedback is provided by a digital servo feedback (HSF) encoder that uses an optical measurement method and relative position detection for rapid homing cycles. The system accuracy is ± 0.5 angular minutes, which indicates the maximum deviation between the commanded and actual shaft angle. The mechanical interface uses a 130 mm centering diameter and a flange size of 192 mm, which helps align the keyed shaft to downstream loads. Cooling is handled by liquid cooling inside the enclosure, and the motor has an ingress protection rating of IP65 for use in dusty or spray-down zones. Electrical power reaches the stator through an output connector on side B, while winding code 035 is matched to the rated current.

In addition to continuous duty capability, the integrated holding brake secures the rotor with 32.0 Nm of torque when power is removed. The motor operates in ambient temperatures from 0 to 40 °C and can be stored from -20 to +80 °C. Insulation class F allows winding temperatures up to 155 °C during operation. Installation is supported up to 1000 m above mean sea level, and a shaft seal helps keep coolant or dust out of the bearing cavity. The shaft seal also helps protect internal parts when the motor is mounted near process equipment. The motor has length code B and frame size 112, which support compact installation where mounting space is limited.
