Product Description:

The MDD071C-N-040-N2T-095GR0 is a permanent-magnet synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it supplies regulated torque and speed to servo axes used in pick-and-place stations, printing machinery, and other automated equipment. The design combines the rotor, stator, and electronic feedback so the associated controller can provide closed-loop position and velocity regulation.

During continuous stall operation, it delivers 6.6 Nm of torque, allowing the axis to hold a load without motion while remaining within thermal limits. When energized at rated frequency, the rotor reaches a nominal speed of 4000 rpm, which sets the available velocity range for cyclic moves. Position data are generated by an integrated multi-turn absolute encoder, and those signals are returned as digital servo feedback (DSF) so the controller can resolve multiple revolutions with single-turn precision. Power and feedback conductors are attached through a sealed connector, which allows a secure cable connection. The motor uses length code C and size 071, while the standard housing and standard dynamic balancing keep vibration within ISO limits.

The mechanical interface uses a centering pilot of 95 mm, providing concentric alignment against the mounting flange and helping keep runout low. All terminals face the right side of the frame, which can simplify cable routing in cabinets that stack several drives. Motion is transferred through a plain shaft without a side-B extension, while a shaft seal blocks lubricant migration toward the bearing and protects the interior against splash ingress. The motor is supplied without a blocking brake, so static holding torque must be furnished by the controller or an external clamp. The absence of an additional shaft end helps keep mass and inertia suitable for high-acceleration profiles.
