Product Description:
The MHD112B-058-PP0-RN servo motor is produced by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. It is used in automation cells where a drive controller commands repeatable rotary motion for positioning, indexing, and material-handling tasks. Torque is transmitted through a keyed shaft, which provides positive mechanical engagement with the driven load. A digital servo-feedback encoder supplies absolute position data to the control loop, allowing the drive to track rotor movement continuously during starts, stops, and speed changes. This closed-loop arrangement helps the axis maintain consistent motion even when the load changes during a cycle.
The motor can hold a continuous torque of 28.0 Nm at standstill, and its stator windings use F-class insulation to withstand the associated thermal load. Cooling is provided by liquid cooling, so heat is removed without relying on external airflow around the housing. The enclosure is sealed to IP65, which helps protect internal parts against dust and low-pressure water jets in industrial environments. Its mounting interface includes a 130 mm centering diameter and a 192 mm flange size. The sealed and cooled design supports stable operation where cabinet air movement is limited. The motor is supplied without a holding brake, uses a shaft seal at the output, and has winding code 058 for its electrical characteristics.
The permissible operating temperature range is 0 to 40 °C, while storage is allowed from -20 to +80 °C when the unit is not in service. Encoder accuracy is rated at ±0.5 angular minutes, supporting precise position control in applications that require small following errors. The encoder provides absolute >4096 revolutions of position reporting, so the drive receives multi-turn position information after power is restored. The motor may be mounted up to 1000 m above mean sea level without derating, and the power, feedback, and cooling connections exit on the right for orderly cable routing in compact enclosures.
