Product Description:
Bosch Rexroth Indramat's MHD071B-035-PP0-UN belongs to the MHD Synchronous Motors series and serves as a servo motor for precise axis control in industrial automation cells, gantries, and packaging machinery. Its electromechanical design matches compatible drive controllers, allowing closed-loop speed and torque regulation while maintaining a compact profile suited for cabinet or machine-frame installation. It is intended for coordinated motion tasks that require accurate positioning and stable response during repeated operating cycles.
The motor delivers a continuous standstill torque of 8.0 Nm, giving enough holding force for moderate load envelopes without overheating. A centering diameter of 95 mm aligns the housing on machine flanges, and the mounting interface follows a square pattern with a 115 mm flange size. Heat generated in the stator windings is removed by liquid cooling, so full rated output remains available even when ambient temperatures are high. Because the unit is supplied without a holding brake, position retention during power-off requires an external mechanical lock. The motor has size code 071 and length code B, while winding code 035 indicates the electrical configuration. The output shaft is fitted with an integral seal that helps keep contaminants away from the bearing area.
Feedback is handled by digital servo feedback that supports absolute position reporting across more than 4096 revolutions, permitting single-turn and multi-turn positioning without homing. Power and signal leads are routed through rotatable connectors, and the power plug can be oriented through 270° to simplify cable runs inside tight enclosures. The keyed shaft provides slip-free coupling to pulleys or gearboxes, and both power and feedback connectors share a common housing for a compact cable interface.
