Product Description:

The MHD131B-024-NG1-RN is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. With motor size 131, motor length B, and winding code 024, it supplies controlled rotary power to conveyors, gantry axes, or processing heads in automated cells. The unit employs digital servo feedback (HSF) for relative position detection. An optically based measurement method transmits the encoder data back to the drive, allowing the controller to regulate torque and speed precisely. This feedback arrangement allows continuous monitoring of rotor movement during closed-loop operation.

Mechanically, the motor can deliver a continuous standstill torque of 48.0 Nm, enabled by a housing that uses liquid cooling to remove heat from the stator. A protection rating of IP65 seals the enclosure against dust and water jets, while a centering diameter of 250 mm and a flange size of 260 mm establish the mounting interface for rigid installation. The plain shaft transfers motion without a keyway, and a shaft seal is fitted to prevent coolant or process contaminants from entering the bearing chamber. The shaft seal also helps retain lubricant around the bearing area during operation. Power reaches the stator through a right-side power connector, and insulation class F materials permit winding temperatures up to 155 °C during cyclic duty.

The integrated holding brake supplies 100 Nm of static torque to secure vertical or indexing loads whenever the drive is disabled. This helps keep the axis fixed when drive power is removed. During operation, the motor maintains positional deviation within ± 0.5 angular minutes, a figure supported by the encoder’s high-resolution optical track. It can operate in ambient temperatures from 0 to 40 °C and can be stored between −20 and +80 °C. Installation altitude must not exceed 1000 m above mean sea level.
