MDD071B-N-060-N2S-095GB2
The MDD071B-N-060-N2S-095GB2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for operation with digital drive controllers where precise torque and speed regulation are required in automated handling, packaging, and assembly stations. By converting controlled three-phase power from an inverter into mechanical rotation, the unit serves as the actuating element for positioning tasks and continuous-duty rotary axes. This operating principle allows the motor to respond quickly to changing command values during indexing, transfer, and other repeating machine movements. In these systems, it can be used on feed axes, transfer mechanisms, and similar motion points that require controlled starts, stops, and stable holding between cycles.
This model delivers a continuous standstill torque of 4.4 Nm, permitting stable force output when the shaft is held against a load. During motion, it can reach a nominal speed of 6000 rpm, which is the maximum repeatable rotational velocity under rated conditions. A blocking brake integrated at the non-drive end supplies 6.5 Nm of holding torque so axes remain locked when the inverter is disabled. This is useful where the load must remain in place after power removal or during a controlled stop. Mechanical centering during mounting is aided by a 95 mm pilot diameter, which helps align the motor accurately on the machine face. Power and feedback cables exit on side B through a keyed connector, and the rotor balance is standard to help limit vibration during operation.
The motor communicates rotor position through digital servo feedback (DSF), enabling the drive to close velocity and position loops without an external encoder. Its compact dimensions correspond to frame size 071 and length code B, which helps the unit fit narrow installation spaces while keeping useful active length. The motor has a single-ended rotor without a side B shaft end, and the housing uses the standard casting. A factory-installed shaft seal helps keep lubricant in place and reduces the entry of fine contaminants at the output end. This arrangement keeps the motor package compact and reduces the number of separate components around the axis.
