MDD071A-N-060-N2M-095GB0
The MDD071A-N-060-N2M-095GB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts controlled three-phase current into precise mechanical rotation for industrial positioning and speed control loops. The 071 frame with the compact A-length housing fits installations where space is limited yet high spindle or axis velocities are needed, such as automated pick-and-place modules or light milling heads. The compact housing also helps the motor fit tightly spaced machine layouts without requiring unnecessary installation depth.
Its mounting geometry centers on a 95 mm centering diameter that aligns the flange to gearboxes or machine frames. Electrical and feedback leads exit on Side B, and a keyed connector permits rapid connection without disturbing conduit runs. The rotor sustains 2.2 Nm of continuous standstill torque, allowing the axis to hold load under thermal steady-state conditions. Under rated excitation, the shaft reaches 6000 rpm, providing short index times while remaining within the permissible stress of the standard housing. A plain shaft without keys transmits torque to couplings, and the standard shaft end omits an extension on the opposite side to conserve axial length. This layout also keeps the cable exit predictable when the motor is mounted close to guarding or neighboring machine elements.
An integrated multi-turn absolute encoder supplies position data through digital servo feedback, eliminating the need for external transducers and enabling high-resolution closed-loop control. Because the unit is shipped without a blocking brake, passive holding torque is not available, so applications that require holding must rely on drive torque or external clamping. Protection against oil or coolant ingress is provided by construction with a shaft seal, which also helps preserve bearing lubrication. Rotor vibration is controlled by standard balancing, maintaining low residual imbalance across the full speed range and supporting long bearing service life. This combination of feedback, sealing, and rotor balance supports stable motion in continuous industrial duty.
