Product Description:

The MDD071B-N-040-N2T-095PA1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it translates commanded current into regulated torque and speed for precise axes in machining centers, handling gantries, and packaging lines. The unit uses motor length code B in the 071 frame and has a standard housing with standard balancing, giving a compact profile that mounts without extra counterweights or vibration-damping hardware. This operating role makes it suitable for positioning, indexing, and synchronized transport applications in automated equipment.

For mechanical alignment, the centering diameter is 95 mm, providing a reference surface that mates the stator body to machine brackets while minimizing radial runout. At standstill, the motor can deliver 4.4 Nm of continuous torque, which indicates its ability to hold or slowly index loads without overheating. Under rated excitation, the shaft reaches 4000 rpm, supporting fast positioning on light-to-medium inertia axes. A blocking brake integrated in the rear housing supplies 3.0 Nm of holding torque, preventing vertical or suspended loads from drifting when power is removed. Position and revolution data are supplied by an integrated multi-turn absolute encoder, allowing the controller to recover the shaft state immediately after power-up.

Electrical terminations face the service side because connections are on side A of the motor. Power and feedback share a single connector, which simplifies cable routing at the motor interface and reduces the number of separate entry points at the rear of the housing. The drive processes position signals through digital servo feedback (DSF), reducing analog drift and supporting high-resolution control loops. Mechanical power is transferred through a shaft with a keyway. There is no shaft extension on side B, which leaves room for a shaft seal that limits lubricant escape.
