Product Description:
The MHD131B-024-NP0-BN servo motor from Bosch Rexroth Indramat is part of the MHD Synchronous Motors series. It is used on closed-loop axes in machine tools, packaging units, and transfer stations, where controlled torque and speed are needed for repeatable motion. A keyed shaft transfers torque to the driven load, and digital servo feedback supplies the controller with rotor position data for accurate interpolation. Because feedback is integrated into the motor, the drive can correct position and speed deviations quickly during contouring, indexing, and repeated start-stop cycles.
Thermal control is handled by liquid cooling, so the stator windings can sustain rated output while the motor housing remains easier to manage in tightly packed machinery. At standstill, the motor delivers 48.0 Nm of torque, which is suitable for resisting load movement before acceleration begins. Its cast housing has IP65 protection to block dust and low-pressure water jets. Position data comes from an optical relative HSF encoder, and feedback accuracy is specified as ± 0.5 angular minutes. The motor is intended for ambient operation from 0 to 40 °C, and power is connected through a connector on side B. A shaft seal helps keep coolant and other contaminants away from the shaft opening.
A centering pilot of 250 mm aligns the motor with precision gearboxes and machine interfaces, while the square flange measures 260 mm on each side to match common mounting patterns. The large pilot and flange also help maintain concentric alignment between the motor shaft and coupled machine elements during assembly. The windings use Class F insulation, allowing winding hot-spot temperatures up to 155 °C without damaging the insulation system under proper operating conditions. Installation is permitted up to 1000 m above sea level, and storage from -20 °C to +80 °C helps protect spare units when the motor is not in service. The motor has length code B and winding code 024, and it is supplied without a holding brake.
