Product Description:
The Bosch Rexroth Indramat MHD131D-012-PG0-AN belongs to the MHD Synchronous Motors series and is supplied as a liquid-cooled servo motor for closed-loop industrial automation. With a motor size of 131 and length code D, the unit suits applications that require high torque within limited mounting depth. Its integrated digital servo feedback encoder provides multi-turn absolute position data, allowing the drive controller to maintain tight velocity and position regulation without an external measuring system. Because the motor is built without a holding brake, stationary loads must be secured by drive torque or a separate mechanical locking device when power is removed.
The centering shoulder is machined to 250 mm, which provides the radial locating reference on the machine frame and helps maintain repeatable alignment. A continuous standstill torque of 160 Nm allows the shaft to produce this level of torque continuously when the stator windings remain at rated temperature. The square flange measures 260 mm on each side, so the housing can be bolted to common brackets or gearbox interfaces. Heat is removed by liquid cooling, which circulates coolant around the stator laminations and supports higher current density than air-cooled designs. The 012 winding code matches the motor's electrical characteristics to compatible drive settings for predictable dynamic response.
The motor uses a plain shaft without a keyway, allowing force-fit coupling hubs to be positioned freely for backlash-free power transmission. Multi-turn encoder operation is specified as absolute >4096 revolutions, so homing after power loss is not required. A shaft seal is fitted at the output end to help block coolant or lubricant ingress and support bearing life in wet or dusty environments. Power and feedback conductors leave the stator through an output connector on side A, which can simplify harness routing when the motor is mounted deep inside a machine frame.
