Product Description:

The MHD131D-024-NG0-AN is a three-phase synchronous servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Designed for closed-loop motion axes in machine tools, packaging lines, and material-handling gantries, it converts drive output into controlled rotary motion with high positional accuracy. The motor interfaces with Indramat drive controllers and delivers continuous torque for indexing, interpolation, or tension-regulated applications common in industrial automation. Its synchronous design also supports stable speed regulation and accurate axis response during changing load conditions.

Its centering pilot measures 250 mm, which aligns the stator housing concentrically with the machine frame and helps minimize radial runout. A continuous standstill torque of 160 Nm indicates the maximum load the motor can hold at zero speed while rated current is maintained. The mounting flange dimension of 260 mm matches high-power gearboxes and couplings used on heavy work axes. Thermal energy is removed through liquid cooling, and coolant flowing around the stator helps keep winding temperature stable during prolonged high-load duty cycles. Rotor position is reported by digital servo feedback (HSF), which supplies high-resolution incremental signals for the controller's real-time current and velocity loops.

The motor uses a plain shaft, so torque is transmitted by shrink-fit or other external drive elements selected for the machine. Overall length code D provides a longer active stack to support the rated torque within this frame size. Winding code 024 balances voltage constant and current demand for compatible medium-voltage drives. Frame size code 131 standardizes the housing diameter within the series. Power cables exit toward side A through an output connector, and the unit is supplied without a holding brake, so external mechanical locking is required when power-off holding is needed. Relative position detection supports homing sequences during startup.
