Product Description:

The MHD131D-024-NG0-BN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. As a closed-loop drive element, it converts controller commands into precise shaft rotation for positioning tables, gantry axes, and similar automation hardware where fast torque buildup and repeatable motion are essential. Its operating profile suits machinery that requires accurate speed regulation and stable positioning during frequent start-and-stop cycles.

The motor delivers a continuous standstill torque of 160 Nm, allowing heavy loads to be held without mechanical clamps. It runs within an ambient range of 0 to 40 °C and is protected by an IP65 housing that blocks dust and low-pressure water jets. Heat is removed through liquid cooling, so rated current can be sustained without excessive temperature rise in the windings. Rotor angle is reported by a digital servo feedback (HSF) encoder, enabling high-bandwidth velocity control and accurate position tracking. Winding code 024 and the 131 frame with D length identify the motor’s electrical matching and physical size for the associated drive. Power connections exit on side B through an output connector, and the motor is supplied without a holding brake. A plain shaft is used for coupling to gearboxes or pulleys.

A centering pilot of 250 mm mates with a square flange measuring 260 mm, providing accurate alignment to adjoining machinery. Closed-loop accuracy is limited to ± 0.5 angular minutes, which supports fine contouring and repeatable motion in precision axes. Class F insulation withstands winding temperatures up to 155 °C, and a shaft seal helps prevent coolant or oil ingress. Storage temperatures from -20 °C to 80 °C allow unpowered warehousing, while operation is permitted up to 1000 m above mean sea level. An optical measurement method supports stable feedback performance under vibration and altitude-related operating changes.
