Product Description:
The MHD071B-061-NG0-UP is an AC servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It is intended for mid-frame automation axes that require repeatable velocity and position control in assembly, packaging, and handling equipment. A relative position encoder inside the housing reports incremental movement to the drive, allowing closed-loop regulation so the load follows commanded profiles without significant overshoot or drift. This feedback arrangement also supports stable correction of speed changes during acceleration, deceleration, and reversing moves.
The motor can deliver 8.0 Nm of continuous torque at standstill, giving machines adequate force for low-speed holding and controlled indexing. A centering flange of 95 mm works with a 115 mm square flange for direct mounting on compatible machine interfaces. Feedback is provided by Digital servo feedback (HSF), which supplies position data needed for accurate speed and motion control. Heat is removed by natural convection, and the housing has IP68 protection against dust and water ingress. That combination supports use in installations where sealed construction is important and added cooling hardware is not desired.
Mechanical output is through a plain shaft with a shaft seal, allowing direct coupling to gears or belt pulleys while helping keep contaminants away from the bearing area. The power connector housing can be rotated through 270°, which makes cable routing easier when space around the motor is limited. Winding code 061 matches the electrical characteristics expected by compatible Rexroth inverters. The B-length housing balances inertia and torque response, and the motor is supplied without a holding brake, so parked loads must be secured by drive torque or an external mechanical lock.
