Product Description:

The MDD071C-N-040-N2T-095GA2 is a synchronous servo unit from the MDD Synchronous Motors series manufactured by Bosch Rexroth Indramat. Intended as a motor for digital drive controllers, it delivers closed-loop rotary motion to handling modules, feeder drives, and assembly gantries. The frame size of 071 and the C length code provide an extended active stack without increasing the external diameter. A standard housing and standard dynamic balancing permit direct flange mounting, while the shaft is supplied only on side A, streamlining layouts that do not need a through shaft.

During continuous standstill, the rotor can generate 6.6 Nm of torque, allowing the axis to hold static loads without overheating. Under running conditions, the winding supports a nominal mechanical speed of 4000 rpm, a value matched to typical 8 kHz PWM drive outputs used in fast indexing applications. When a motion command is interrupted, an internal blocking brake supplies 6.5 Nm of holding torque so vertical or suspended loads remain fixed after power is removed. Position and commutation data are supplied by an integrated multiturn absolute encoder, ensuring error-free homing even after extended shutdowns. Mounting concentricity is set by a 95 mm centering diameter that mates with Rexroth standard servo flanges.

Feedback to the drive is transmitted through digital servo feedback (DSF) signals that travel alongside power conductors in a keyed connector mounted on the motor end bell. The wiring exits on side A, which matches cabinet layouts that favor short cable runs toward the drive rack. Mechanical output is via a plain shaft that includes a fitted shaft seal to keep lubricant inside and contaminants out. Because the model uses standard balancing and a standard housing, no additional coupler compensation or environmental shrouding is required during integration.
