Product Description:

The MDD071B-N-030-N2S-095PR0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where precise torque and velocity loops are managed electronically. In factory automation, this model converts drive current into controlled mechanical rotation so that indexing tables, pick-and-place axes, or packaging spindles follow programmed motion profiles. This operating role makes it suitable for axes that require repeatable starts, stops, and speed changes during automated cycles.

This unit can develop a continuous standstill torque of 4.4 Nm, enabling stable holding or slow-speed operation without overheating. When driven by an inverter at rated frequency, the rotor reaches a nominal speed of 3000 rpm, giving a balanced compromise between throughput and positional accuracy. Position feedback is delivered through digital servo feedback (DSF), allowing the controller to read position data and correct following error in real time. The feedback link supports stable motion during acceleration, low-speed running, and position correction. A centering diameter of 95 mm supports coaxial alignment to gearboxes or machine frames, and the motor is supplied without a blocking brake, so any static load retention must be handled by external mechanics or drive torque.

Standard balancing minimizes vibration, and the housing uses the standard envelope for frame size 071 with B length. A shaft seal helps protect the shaft opening from contaminants, while the output shaft itself is machined with a keyway to transmit torque through keyed couplings or pulleys. Power and feedback leads exit through connectors mounted on the right side, which simplifies wiring when the motor is installed on right-hand machine walls. The motor also uses a single-ended shaft configuration and standard circular connectors, which support straightforward integration in compact multi-axis assemblies.
