Product Description:

The MHD131D-024-NP1-BN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It serves as a rotary actuator in closed-loop automation systems, where the motor converts drive commands into controlled torque and repeatable shaft motion for transfer lines, machine tools, and handling equipment. The unit combines a keyed shaft for positive mechanical coupling with digital servo feedback, allowing the connected drive to monitor rotor movement closely and keep the commanded position synchronized with the driven load. This arrangement supports accurate motion control in applications that require stable response during indexing, feed movement, and holding tasks.

In steady operation, the motor can provide 160 Nm of continuous torque at standstill, making it suitable for low-speed holding and precise feed applications. A brake at the non-drive end supplies 100 Nm of holding torque, so the axis can remain in position when power is removed. Thermal load is managed through liquid cooling, which helps keep winding temperature within acceptable limits during high-current operation. The motor has a flange size of 260 mm for secure mounting on machine structures, and the enclosure is rated IP65 to resist dust ingress and water jets in industrial environments.

The housing uses a pilot diameter of 250 mm to support accurate centering during installation. Relative position feedback is provided by a high-speed HSF encoder with accuracy to within ± 0.5 angular minutes, which supports precise motion correction by the drive. Electrical power enters on side B through an output connector, helping keep cable routing orderly near the machine frame, while a shaft seal protects the front bearing area. The motor is intended for operation in ambient temperatures from 0 to 40 °C, uses insulation class F, and can be stored from -20 to +80 °C at elevations up to 1000 m above sea level. The motor also uses winding code 024 and a size 131, length D frame.
