Product Description:

The MHD112D-027-NP3-BN servo motor is manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It is designed for industrial automation axes that demand precise velocity and position control, using relative feedback from a high-speed digital encoder to synchronize motion with the drive controller. This feedback arrangement helps the axis maintain stable response during repeated starts, stops, and direction changes. Because the encoder feedback is digital, the motor can support closed-loop regulation without separate external sensing hardware. The motor’s keyed output shaft, side-B power connector, and liquid-ready housing allow direct integration into packaging lines, gantries, or forming equipment where space, cooling, and repeatable alignment are critical.

The motor can deliver a continuous standstill torque of 48.0 Nm, allowing it to hold demanding loads without overheating during rated duty cycles. The motor has an IP65 enclosure, so dust and low-pressure water jets do not impair operation. Heat is removed by liquid cooling, which keeps winding temperature below insulation class F limits even during cyclic acceleration. This cooling method supports compact machine layouts where airflow around the motor body is limited. The mechanical interface uses a 192 mm square flange, while a 130 mm centering diameter keeps the stator concentric with coupled hardware and helps reduce runout and vibration.

The integrated holding brake applies up to 70.0 Nm, so vertical or suspended loads remain stationary when power is removed. For motion accuracy, the optical encoder and digital servo feedback maintain system deviation within ± 0.5 angular minutes, supporting tight positional tolerances across repetitive cycles. Storage conditions from -20 to +80 °C protect magnets and bearings when the motor is not in service, and the operating range of 0 to 40 °C suits typical plant conditions. Maximum installation elevation is 1000 m above sea level, and winding code 027 indicates the electrical characteristics used by the matching drive. The motor uses relative position measurement, and the shaft seal helps keep coolant or oil out of the housing.
