Product Description:

The MHD115C-035-NG1-BA is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. In automated plants, it converts drive current into precisely controlled rotary motion, letting controllers position tooling, conveyors, or gantry axes with repeatable accuracy under closed-loop feedback. This supports accurate speed regulation and repeatable positioning during continuous machine cycles.

Its continuous standstill torque reaches 70.0 Nm, providing reserve for holding heavy inertial loads. Thermal energy leaves the aluminum housing through natural convection, eliminating fans or liquid circuits. A rigid mounting interface with a 192 mm square flange simplifies alignment, and the enclosure carries an IP65 rating against dust and low-pressure water jets. Feedback is delivered by a digital servo feedback (HSF) encoder that is read optically and supplies relative position data to the drive. Winding code 035, motor length C, and size 115 indicate the electrical constants and stack height, while Class F insulation withstands 155 °C winding temperature. Power reaches the stator through a connector on side B, and a shaft seal helps keep coolant from entering the interior.

A centering diameter of 180 mm guides the motor into the machine frame, and the rotor has a plain shaft so couplings or timing pulleys can clamp directly onto the journal. The integrated holding brake clamps the shaft when supply power is absent, safeguarding vertical or suspended loads. Within an ambient range of 0 to 40 °C, the drive system holds a total positioning error of only ±0.5 angular minutes, enabling tight contouring and repeatable pick-and-place sequences. Storage is permitted between −20 and +80 °C, and operation remains full-rated up to 1000 m above mean sea level.
