Product Description:

The MHD131D-024 is a servo motor manufactured by Bosch Rexroth Indramat and assigned to the MHD Synchronous Motors series. Within an automation cell, it serves as the rotary actuator that drives gantries, conveyor axes, or tool spindles under closed-loop control. The motor integrates with Rexroth digital drives, allowing position, speed, and torque regulation that matches real-time process demands while keeping overall dimensions within the heavy-duty 131 frame class. That combination supports repeatable positioning, controlled acceleration, and stable holding behavior during changing load conditions.

A continuous standstill torque of 160 Nm lets the motor hold static loads without overheating when the shaft is locked by the control loop. The centering diameter of 250 mm aligns the housing on machine mounting pilots, and the square flange measures 260 mm across to provide a bolt pattern for large gearbox or direct-coupled assemblies. Frame code 131 corresponds to the stator outer diameter and matches the thermal mass and magnetic loading used for this motor family. The square flange and centering pilot also help keep shaft alignment consistent when the motor is mounted to large machine structures. The motor uses resolver feedback, along with a common connector orientation and sealing concept found across related MHD units.

Electrical configuration is identified by winding code 024, which sets the nominal voltage and current that the matching inverter must deliver. Stack length code D extends the active iron and copper section so higher torque can be produced without increasing the frame diameter. The housing is built to maintain dimensional alignment between the motor and driven mechanics during installation. It also uses thermal sensors and feedback elements suited to closed-loop motion rather than simple constant-speed operation. This arrangement helps the drive maintain predictable electrical behavior during acceleration, holding, and speed changes.
