Product Description:
The MHD131D-024-PP1-AN is a servo motor engineered by Bosch Rexroth Indramat within the MHD Synchronous Motors series. As a rotary actuator for industrial automation, it converts commanded electrical power into precise mechanical motion for positioning or speed-regulated axes. The motor is built in size 131 with length code D, and it uses winding code 024 so its electrical characteristics match compatible drive controllers. This configuration suits machine axes that require repeatable motion, controlled acceleration, and stable torque response during continuous operation.
At standstill the motor can deliver 160 Nm of continuous torque, allowing heavy loads to be held without overheating. Its enclosure is rated to IP65, which helps keep out dust and withstand low-pressure water jets in exposed installations. A housing equipped for liquid cooling removes heat directly from the stator jacket, helping the motor maintain output in confined machine frames. Position feedback comes from an optical digital encoder mounted on a centering shoulder that measures 250 mm in diameter, and that shoulder also helps align the flange with adjacent gearboxes. A flange circle of 260 mm provides the bolt pattern used for mechanical mounting.
To secure the axis during power loss, the integral holding brake supplies 100 Nm of static torque and engages automatically when the drive is disabled. Closed-loop performance is reinforced by an absolute multi-turn measuring system with a system accuracy of ± 0.5 angular minutes, supporting high repeatability after startup and during position recovery. The motor routes power leads to side A through an output connector, and the keyed shaft includes a fitted seal to limit lubricant migration into the bearing chamber. Insulation class F windings permit operation in ambient temperatures from 0 to 40 °C, while storage is allowed within a range of -20 to +80 °C. Service height is limited to 1000 m above mean sea level so cooling performance remains consistent.
