Product Description:

The MDD071A-N-040-N2S-095GB2 is a servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts drive current into precise mechanical rotation for positioning and velocity control in automated machinery. The unit follows the series size and length coding, including length code A, which gives it a compact frame with a standard housing for cabinet or machine-bed installation. Because it is intended for closed-loop operation, the motor responds quickly to command changes from the associated drive. In packaging, handling, and light assembly equipment, this format supports precise start-stop motion during repeated duty cycles without requiring a large installation envelope.

This model delivers a continuous standstill torque of 2.2 Nm, allowing it to hold loads steadily without overheating when stalled. Its rated speed reaches 4000 rpm, so a matched drive can command high shaft speed while maintaining responsive control. Power and feedback conductors exit on Side B, and a keyed connector simplifies cable routing at the rear of the motor. Position information returns through digital servo feedback (DSF), enabling tight control loops in compatible drive controllers. The 95 mm centering pilot helps align the motor accurately with a gearbox or direct-driven load.

A blocking brake is integrated and supplies 6.5 Nm of static torque, so vertical or suspended axes remain secure during power-off states. The mechanical interface uses a plain shaft with a fitted shaft seal that helps keep dust and coolant away from the bearing area. This arrangement is useful where the driven load must stay in place after power is removed. The shaft seal also helps reduce the entry of fine debris in machines that operate near process dust or light coolant splash. The motor uses size code 071, which places it in a compact frame for smaller servo axes.
