Product Description:

The MDD071A-N-040-N2T-095PR2 is manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. It is intended for use with digital drive controllers in positioning axes, packaging actuators, and other automated motion systems that require repeatable control. By converting commanded current into regulated shaft rotation, the motor supports accurate starts, stops, and speed changes during cyclic machine operation.

The motor is positioned against machine frames by a centering pilot of 95 mm, which helps keep the stator bore aligned with the driven load. When energized, the stator produces a continuous standstill torque of 2.2 Nm, allowing the axis to hold a low-inertia load without overheating. During motion, it can reach a nominal speed of 4000 rpm, which sets the normal operating speed range for the matching drive. An integrated blocking brake at the non-drive end delivers up to 6.5 Nm of holding torque, so suspended or vertical loads can remain stationary when power is removed. Torque is transferred through a shaft with a keyway, which helps prevent slip when pulleys or rigid hubs are mounted, and the standard balancing code helps reduce residual vibration at rated speed.

Electrical terminations exit on the right side through a threaded connector, which helps reduce cable loops when the motor is installed in tight spaces. Angular position data is supplied by an integrated multiturn absolute encoder through DSF digital servo feedback, enabling the drive to close position and velocity loops without external sensors. The motor uses frame size 071 with the short A length code, so it fits where installation space is limited. A contact shaft seal helps limit dust or coolant ingress, and the housing follows the standard series pattern without a side-B shaft extension.
