Product Description:
The MHD131B-024-NG0-AN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Built for industrial automation axes, it converts electrical power from the drive into controlled rotary motion that can be synchronized with other machine elements. The motor’s plain shaft and feedback arrangement give machine builders a compact actuator for accurate closed-loop control in positioning and process speed regulation.
At standstill, the rotor can deliver 48.0 Nm of continuous torque, allowing stable force output for holding or low-speed machining operations. Heat generated under this load is removed by the motor’s liquid cooling jacket, so thermal limits are reached more slowly than with air-cooled designs. Position data is returned through digital servo feedback (HSF), which combines an optical measuring method with relative coding to match high-speed drives. This feedback contributes to a system precision of ± 0.5 angular minutes, helping keep contour errors low on multi-axis equipment. An enclosure rating of IP65 protects the internal windings and bearings from dust ingress and water jets, supporting installation near cutting fluids or washdown areas without additional housings. The motor is supplied without a holding brake, so external clamping must be considered when power-off retention is required, and a shaft seal helps prevent oil migration along the journal.
Mechanical integration is simplified by a centering diameter of 250 mm that aligns the stator on the machine frame, while a flange size of 260 mm matches standardized mounting patterns for the 131 frame. Class F insulation permits winding temperatures up to 155 °C, complementing the liquid circuit during intermittent overloads. The motor operates in ambient temperatures of 0 to 40 °C and may be stored between −20 and +80 °C without damage. Installation is permitted up to 1000 m above mean sea level, and the power connector is located on side A for clearer cable routing. Winding code 024 sets the electrical characteristics used by matching drive inverters, and motor length code B identifies the stator stack used in this version.
