Product Description:

The MDD071C-N-040-N2T-095GR2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and part of the MDD Synchronous Motors series. Designed for use with digital drive controllers, it serves automated handling equipment and machine tools where tight velocity and position loops are required. The unit converts commanded current into controlled rotary motion so actuators, indexing tables, or spindles follow programmed motion profiles with repeatable accuracy. This makes it suitable for axes that must start, stop, and reverse direction with consistent control.

A centering diameter of 95 mm supports accurate mounting alignment with standard flange patterns. The motor uses frame size 071 and length code C, giving a medium power envelope that supports a continuous standstill torque of 6.6 Nm during holding and low-speed operation. Under full excitation, it sustains a nominal shaft speed of 4000 rpm, allowing direct coupling to belts or gear stages without overspeed. Rotor balancing to the standard grade helps reduce vibration during normal operation and supports smooth coupling to connected machine elements. Power and feedback cables exit on the right side, and the round connector provides a compact cable interface without opening the enclosure.

Control accuracy is supported by an integrated multiturn absolute encoder that reports rotor position through digital servo feedback, allowing the drive to track multiple mechanical revolutions without repeated homing. For load holding during power loss, the integral blocking brake supplies 6.5 Nm of torque when de-energized. The output end includes a shaft seal, and the shaft is delivered as a plain shaft, which avoids keyway stress concentrations in couplings. This arrangement supports direct coupling where a keyed shaft is not required and helps protect internal components from dust and light splash. The motor also has a standard housing with a single shaft end on side A only, which helps preserve installation space in shallow machine layouts.
