Product Description:

The MDD071B-N-040-N2T-095PB0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed to pair with digital drive controllers, it supplies commanded rotation for indexing tables, pick-and-place arms, and other industrial automation axes. The unit combines electronic commutation with permanent-magnet rotor behavior to provide rapid speed changes while maintaining precise shaft positioning under closed-loop control. This supports repetitive motion tasks where the drive must respond quickly to changing speed commands and settle accurately at target positions.

The motor’s centering pilot measures 95 mm, allowing accurate alignment against gearheads or mounting flanges while the rotor remains under standard dynamic balancing to limit residual vibration. Power and feedback cabling exit on Side B through a sealed connector, which helps keep cable routing orderly around the machine frame. At standstill, the unit delivers 4.4 Nm of continuous torque, and this output is tracked by an integrated multiturn absolute encoder that returns absolute position without a reference move after startup. Because the design is without a blocking brake, any vertical or suspended load must be held by external hardware or commanded drive torque. When supplied with rated current, the rotor can accelerate to 4000 rpm, giving a broad speed range for indexing or contouring applications. A shaft seal is installed to protect the bearing area from contamination and lubricant migration.

Drive controllers read the rotor’s position via Digital servo feedback (DSF), a signal format used with the encoder so commutation and position data reach the control loop without extra alignment steps. Mechanical power exits through a keyway machined in the single shaft, allowing a hub or coupling to transmit torque securely to the load. The motor uses frame size 071 and length code B, which keep the housing compact for machines where installation space is limited and moving mass should stay low. The single-shaft arrangement also leaves the non-drive end closed, which helps preserve the compact overall outline of the motor.
