Product Description:

The MHD131B-024-PG0-AN is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It converts controlled three-phase power from a drive controller into precise rotary motion, enabling coordinated positioning, contouring, and synchronized speed holding in automated production equipment. By combining a compact frame with digital feedback and a high-density winding, the unit supports continuous duty on spindle drives, gantry axes, and indexing tables where repeatable accuracy and rapid response are required. Its closed-loop behavior helps the connected axis stay stable during repeated starts, stops, and load changes.

This model delivers a continuous standstill torque of 48.0 Nm, sustained by the motor’s liquid cooling housing that removes heat directly from the stator. The mechanical interface uses a centering diameter of 250 mm and a 260 mm square flange, allowing rigid seating on heavy machine frames. Position feedback is provided by digital servo feedback with an integrated optical encoder that supports absolute reporting beyond 4096 revolutions and system accuracy of ± 0.5 angular minutes. The encoder data allows the drive to track rotor angle continuously for accurate commutation and smooth speed regulation. The motor uses winding code 024, while size 131 and length B indicate the active iron volume. Power conductors exit toward side A through an output connector, which helps keep cable routing orderly on large axes.

The enclosure carries a protection rating of IP65, and the shaft seal helps keep liquids and dust away from the bearings during normal industrial use. Operation is permitted from 0 to 40 °C, while storage or transport can range from -20 to +80 °C; these limits apply at installation heights up to 1000 m above sea level. The motor uses a plain shaft interface and comes without a holding brake, so static load retention must be provided by the drive or an external mechanism. This shaft style suits couplings that clamp directly to the output end without a keyed connection. Insulation class F supports the winding system during continuous industrial operation.
