Product Description:

The MDD071B-N-040-N2T-095PA2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It operates as a motor for digital drive controllers, translating commanded current into controlled rotary motion for positioning tasks in automated cells. This operating principle supports repeatable speed regulation and accurate axis movement in packaging, assembly, and transfer applications. The unit uses motor size 071 and length code B, and it is supplied with standard housing, standard dynamic balancing, and a single shaft end to fit space-restricted, multi-axis frames.

At standstill the motor supplies a continuous torque of 4.4 Nm, allowing closed-loop drives to hold loads without excess heating. When the winding frequency reaches nominal values, the rotor achieves 4000 rpm, supporting rapid indexing cycles and short transfer movements. Mechanical centering is performed on a 95 mm pilot diameter, and service wiring exits on Side A through a molded connector that simplifies cable routing. Position and velocity signals are returned as digital servo feedback (DSF), so the drive can apply high-bandwidth current control and stable speed regulation. The single output shaft is cut with a keyway, creating a positive mechanical interface for pulleys or couplings while minimizing backlash during direction changes.

A blocking brake integrated on the rear housing produces 6.5 Nm of static torque to secure vertical loads when power is removed. Motion history is preserved by an integrated multi-turn absolute encoder, enabling immediate resumption of operation after an interrupted cycle without a reference run. To keep lubrication in and contaminants out, a shaft seal is fitted around the journal, making the motor more suitable for general-purpose industrial installations. This layout suits machinery that pauses frequently between indexed moves and then restarts under closed-loop control.
