Product Description:
The MHD131D-024-NP1-AN is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It uses winding code 024, corresponds to motor size 131, and carries the length designation D. The unit supplies closed-loop rotary motion for industrial automation axes where electronic drives issue position, speed, and torque commands. Its design supports high-load cyclic applications in packaging, printing, and material handling. This role suits machinery that must accelerate, hold position, and reverse direction repeatedly during normal production cycles.
At standstill, the motor delivers 160 Nm of continuous torque, allowing heavy tooling to remain stationary without additional gearing. The housing meets IP65, so internal components are sealed against dust and directed water jets. Rotor position is monitored through Digital servo feedback (HSF), which is read optically and interpreted as relative data by the drive. Mechanical alignment to adjacent machinery is simplified by a 250 mm centering diameter and a 260 mm square flange. Heat is removed through liquid cooling, which helps maintain steady temperatures while the keyed shaft transmits power. Electrical energy reaches the stator through an output connector on side A, which can help keep cable routing orderly in compact cabinets. A positive shaft seal is installed to limit oil ingress during washdown duty.
The built-in holding brake exerts 100 Nm when the drive is disabled, preventing back-driving on vertical axes. Motion repeatability relies on system accuracy of ±0.5 angular minutes, which suits point-to-point tasks that require fine angular positioning. Windings are insulated to Class F, helping the stator tolerate cyclic thermal loading while operating within an ambient range of 0 to 40 °C. Installation is permitted at heights up to 1000 m above mean sea level, and extended storage is allowed between -20 and +80 °C. The optical measurement method avoids contact wear in the feedback path, which supports stable feedback behavior through repeated starts, stops, and holding periods.
