Product Description:

Bosch Rexroth Indramat manufactures the MDD071C-N-030-N2S-095GB0 synchronous motor for digital drive controllers in the MDD Synchronous Motors series. The unit uses the 071 frame size with C length and converts stator current into regulated torque for positioning tables, pick-and-place heads, and other motion axes in automated cells. Its compact housing helps keep moving mass low, while the standard balancing grade reduces residual vibration that could affect motion quality. That makes it suitable for packaging, assembly, and handling equipment that depends on repeatable motor response from cycle to cycle.

The motor seats against a centering pilot of 95 mm, allowing repeatable coaxial alignment with the driven machine. Power and encoder leads exit on side B through a single industrial connector, which simplifies cable routing where cabinet space is limited. At standstill, the electromagnetic package delivers 6.6 Nm of continuous torque, and the magnetic circuit is tuned for a rated speed of 3000 rpm, matching many Indramat drive settings. A plain shaft transfers motion without keys, and the omitted shaft end on side B leaves more room for close-coupled gear stages or compact machine interfaces. Housing and winding insulation follow the standard series versions, so the motor matches common MDD mounting and cooling arrangements.

This configuration is supplied without a blocking brake, so position retention during power loss must be handled by external mechanics or by controlled drive torque. Rotor position is reported through Digital servo feedback, enabling high-resolution velocity and position loops in the controller. The stator stack identified by code C provides additional active length over shorter variants and adds thermal mass for continuous-duty operation. Internal labyrinths work together with a shaft seal to protect the bearings from coolant spray and airborne oil. This layout is suitable for precise rotary motion in enclosed machinery where feedback quality, sealing, and stable torque output are important.
