Product Description:
The MHD131D-024-PG1-AN servo motor is built by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. Designed for closed-loop drive systems in machining centers and automated material handling, the unit converts electrical energy into precise rotary motion for dynamic axis control. The motor has size 131 mechanics, length code D, and a 260 mm mounting flange, while winding code 024 corresponds to the electrical characteristics used with compatible drives. A plain shaft with an integral shaft seal transmits torque directly, and the power and feedback conductors exit on side A through an output connector. Integrated digital servo feedback supplies real-time rotor position data to the controller.
At standstill, the motor can deliver a continuous 160 Nm of torque, allowing heavy loads to be held without overheating. The centering diameter of 250 mm aligns the stator housing concentrically with machine frames and minimizes runout. The enclosure is rated IP65, so dust and low-pressure water jets are kept away from internal components during operation. Heat generated in the stator windings is removed by liquid cooling, which keeps copper temperatures below the Class F insulation limit and supports high duty cycles. A holding brake rated at 100 Nm is fitted, and it clamps the shaft mechanically when the drive is disabled to help prevent vertical axes from drifting.
The integrated optical system resolves absolute shaft position with a system accuracy of ± 0.5 angular minutes, and absolute multiturn tracking for more than 4096 revolutions eliminates homing on power-up. The specified operating ambient of 0 to 40 °C covers most shop-floor environments, while warehouse storage can range from -20 to +80 °C without degrading magnetic properties. Installation is permitted up to 1000 m above mean sea level, and the optically measured feedback remains stable at that height.
