Internal Product Review
The MHD112D-027-NP3-RN is a servo motor engineered for demanding motion applications, with liquid cooling supporting stable thermal performance. Digital servo feedback (HSF) and ±0.5 angular minutes system accuracy make feedback quality a strong point in precision axes. IP65 protection and a 70.0 Nm holding brake add valuable durability and secure axis retention.

Product Description:
The MHD112D-027-NP3-RN belongs to the MHD Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is a servo motor intended for closed-loop positioning and speed tasks in automated machinery, supplying precise electromechanical power where repeatable motion is required on packaging lines, machining centers, and handling systems. This type of motor is suited for axes that must start, stop, and reverse with consistent response under varying load conditions. Power enters through a right-side power connector, and the Size 112, Length D frame keeps installation dimensions consistent with other units in the series.
The motor can deliver a continuous standstill torque of 48.0 Nm, which is the torque it can hold without rotation while energized. A protection rating of IP65 blocks dust and water jets so the housing may be mounted directly on equipment. Position data are captured with digital servo feedback (HSF). This optically based encoder supports relative position detection with system accuracy of ±0.5 angular minutes, and the signal allows the drive to monitor rotor position continuously during motion. Mechanical attachment is through a 192 mm square flange and a 130 mm centering diameter, while the keyed shaft transfers torque to the driven element. The square mounting face helps seat the housing accurately against machine plates or gearbox adapters. Internal liquid cooling removes heat, allowing the F-class windings with code 027 to operate continuously.
An integral holding brake provides 70.0 Nm of static torque so vertical or suspended axes remain fixed when power is off. Acceptable ambient temperatures for operation span 0 to 40 °C, and the motor may be stored between -20 to +80 °C without damage. Installation is supported at elevations up to 1000 m above mean sea level without derating. A shaft seal is fitted to prevent coolant or lubricant ingress, and liquid cooling keeps enclosure temperature stable even at maximum duty. The shaft seal also helps protect the bearing area when the motor is installed near lubricated or wet machine zones.
