Product Description:

The MDD071B-N-040-N2T-095GR1 is a synchronous motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for integration with digital drive controllers, the unit converts controlled current into rotary motion for positioning axes, feeders, and indexing tables in industrial automation environments. Its synchronous design supports precise speed and position control when it is paired with a compatible controller. This motor type is well suited to machines that require repeatable starts, stops, and short indexing movements. Power and feedback connections use a molded connector on the right side of the motor, which helps keep cable routing clear of adjacent modules.

A centering diameter of 95 mm allows accurate location in the mounting flange, and the motor uses a frame size of 071 in a standard housing form. Length code B provides the stack depth required for thermal dissipation at a continuous standstill torque of 4.4 Nm. Speed capability reaches 4000 rpm for cyclic duties, giving the motor a broad operating range for automated motion. The motor uses a plain shaft on side A only, while the shaft end on side B is omitted. Internal bearings support radial loads, and the compact housing helps the motor fit into machine sections where installation space is limited.

Operational holding is supplied by a blocking brake that exerts 3.0 Nm when the drive is disabled, helping prevent load drift on vertical axes. Position data is captured by an integrated multi-turn absolute encoder, and its signals are transmitted as digital servo feedback (DSF) so closed-loop position remains available after power cycles. This feedback arrangement supports accurate monitoring of rotor position during repeated indexing motion. A fitted shaft seal limits the ingress of coolant or dust along the journal, supporting reliable operation in enclosed industrial machinery.
