Product Description:

The MDD071A-N-060-N2T-095GR1 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Intended for digital drive controllers, the unit supplies precise rotary motion and secure holding capability for compact automation axes, conveying systems, and assembly stations where rapid acceleration, repeatable positioning, and continuous duty are required. Its compact frame also suits machine sections where installation space is limited but stable closed-loop motion is still needed. That combination makes it suitable for pick-and-place units, feed axes, and other motion tasks that need short cycle times and dependable stop positions over long operating periods.

At a nominal speed of 6000 rpm, the frame size 071 rotor reaches the peripheral velocity needed for fine indexing cycles, while continuous standstill torque of 2.2 Nm supports position holding without thermal overload. A blocking brake delivers 3.0 Nm to secure vertical loads when power is removed. Power and feedback leads exit on the right side through a sealed connector, which helps simplify cable routing. Accurate mechanical registration is provided by a flange centered on a 95 mm pilot, and the A-length stator helps keep the motor compact. The housing uses the standard series cooling design, and the shaft end has no side-B extension, so couplings or pulleys can be mounted close to the bearing.

The integrated multi-turn absolute encoder records position across 4096 mechanical revolutions and sends it to the drive through digital servo feedback, allowing startup without a homing move after power-up. A plain shaft helps reduce fretting during high-speed operation, while the factory-installed shaft seal helps block coolant ingress and retain grease in horizontal or vertical mounting positions. This arrangement gives the drive continuous position information during motion as well as retained absolute position information after shutdown. The encoder supports accurate position reporting during repeated cycles, and the blocking brake provides holding support when the axis must remain stationary with the drive de-energized.
