Product Description:

The MHD131D-024-PP2-AN is a rotary servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Optical digital servo feedback is integrated to deliver rotor position data directly to drive controllers, allowing closely coordinated motion in machining centers, packaging cells, and assembly robots. Because the feedback device is built in, no separate external position sensor is needed on the axis. A keyed shaft with a factory shaft seal supports direct coupling to gearboxes or pulleys while helping keep internal components isolated from process fluids. The motor uses frame size 131 with length class D, so it fits high-torque axes that need a compact installation profile and stable mechanical support.

The motor produces a continuous standstill torque of 160 Nm, which provides steady force for holding loads or feeding at very low speed without thermal overload. A centering diameter of 250 mm aligns the motor accurately in the machine housing, and the 260 mm flange helps spread mechanical load during acceleration and deceleration. Heat is removed by liquid cooling, which supports rated current even where surrounding airflow is limited. The housing is rated IP65, so dust and low-pressure water jets are kept away from the bearings, windings, and encoder cavity. That sealing level suits equipment exposed to coolant mist, airborne dust, or routine washdown splash. Closed-loop positioning accuracy reaches ±0.5 angular minutes, supporting fine interpolation and repeatable contouring moves.

An integrated holding brake supplies 240 Nm of braking torque to secure vertical or suspended axes when drive power is removed. The motor is intended for ambient temperatures from 0 to 40 °C, while storage is permitted from -20 to 80 °C when the unit is not in service. Class F insulation supports reliable electrical separation during normal operation and storage. Winding code 024 identifies the electrical configuration used for this motor, and the absolute feedback system tracks position over more than 4096 revolutions, so the axis can retain multi-turn position information after power loss. Installation is permitted up to 1000 m above sea level, and the power output connector is oriented to side A to simplify cabinet-directed cable routing.
