Product Description:

The MHD112B-048-PP1-AN servo motor is produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. As a brushless AC unit, it converts electrical energy into precise rotary motion for industrial automation axes that require closed-loop position control. Its brushless design avoids commutator wear and supports smooth operation under servo drive control. The device belongs to motor size 112, has the B length designation, and uses an output connector on side A for cabling.

At standstill it maintains 28.0 Nm of continuous torque, enabling stable holding power without overheating. Heat is removed through liquid cooling, so coolant flow around the stator helps keep winding temperatures within the Class F insulation limit. The mechanical interface uses a 130 mm centering diameter and a 192 mm flange for alignment with compatible machine or gearbox mounts. An ingress rating of IP65 protects the stator housing against dust and low-pressure water jets. Rotor position is monitored by digital servo feedback with an optical measurement method that supplies absolute data over more than 4,096 revolutions, supporting accurate velocity control.

For static positioning, the integrated holding brake provides 22.0 Nm of braking torque, and the motor has a keyed shaft with a shaft seal to help prevent slip and lubricant migration. The brake supports load retention when motion stops, while the sealed shaft arrangement helps protect the bearing area during operation. Over an operating range of 0 to 40 °C, the motor maintains a system accuracy of ±0.5 angular minutes. Storage is permitted from -20 to +80 °C, and installation is allowed up to 1,000 m above sea level. Insulation Class F provides thermal margin for intermittent overloads, and winding code 048 identifies the electrical winding used in this model.
