Product Description:

The MHD115C-024-NG1-BA is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Within multi-axis industrial automation, it converts drive current into controlled mechanical torque so that positioning tables, gantries, and processing heads follow precise motion profiles. The motor is intended for closed-loop motion tasks where stable torque production and accurate rotor feedback are needed throughout repeated cycles. This supports accurate starts, stops, and dwell positions in automated machinery. Motor size 115 with length code C gives it a longer housing in this frame, and the output connector exits on side B to support orderly cable routing.

This model can hold a continuous torque of 70.0 Nm at standstill during closed-loop regulation. The enclosure is rated IP65, which keeps out dust and low-pressure water jets during operation. A 192 mm flange with a 180 mm centering diameter helps align the motor to gearboxes or machine frames and supports repeatable mounting. Rotor angle data come from Digital servo feedback (HSF) measured optically, allowing the drive to commutate with high precision. The 024 winding uses insulation class F and may operate continuously within an ambient range of 0 to 40 °C. An integrated holding brake clamps when power is removed, which helps keep the shaft from turning at rest.

Cooling is provided by natural convection, so no forced-air or liquid circuit is required around the motor housing. Combined electronic and mechanical tolerances give positioning accuracy of ± 0.5 angular minutes during position control. A relative position detection system lets the controller establish the shaft reference after each power cycle. Long-term storage is permitted from -20 to +80 °C when the motor is not in service. The motor can be installed at heights up to 1000 m above mean sea level without auxiliary cooling. It also uses a plain shaft with a shaft seal, which supports clean operation at the output end and helps protect internal components.
