Product Description:

The MHD071B-061-NG2-UN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It is intended for closed-loop industrial motion, where drive current is converted into controlled rotary force for indexing tables, packaging axes, and other automated stations. Its plain shaft can be coupled directly to pulleys or gearboxes, and the integrated holding brake helps keep the axis in position when power is removed or motion must stop. Because it works with a matching drive in closed loop, commanded speed and position can be corrected quickly as load conditions change during repetitive machine cycles.

The motor mounts to machinery through a standard flange that measures 115 mm, while a centering diameter of 95 mm keeps the motor aligned with the connected machine face. At standstill, it can deliver 8.0 Nm of continuous torque, which suits moderate inertia loads without excessive thermal buildup. A jacket around the housing provides liquid cooling, so heat is transferred to an external circuit instead of the surrounding cabinet air. This arrangement helps maintain thermal stability during continuous duty and reduces the amount of waste heat released near neighboring components. The power connector can rotate through 270°, which helps with cable routing in tight spaces, and the spring-applied brake supplies 6.5 Nm of static holding torque for vertical axes.

Rotor position is monitored through Digital servo feedback, allowing the drive to process relative position signals for accurate velocity and position control. The electrical characteristics correspond to winding code 061, and the compact Motor size 071 with length code B helps limit overall mass on moving machine members. That combination supports responsive motion on gantries and similar mechanisms where moving mass affects acceleration and settling behavior. Power and feedback connections share one orientation, the rotatable plug helps reduce cable strain, and a shaft seal limits the migration of coolant or oil along the plain shaft in wet processing areas.
