MDD071B-N-060-N2S-095GL1
The MDD071B-N-060-N2S-095GL1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts inverter power into mechanical rotation for positioning and speed-controlled axes in automated machinery. This operating role makes it suitable for feed drives, transfer units, and other motion systems that require stable torque response and accurate speed regulation. The unit has motor size 071 with length code B, giving a compact footprint for mid-range power demands while keeping mass and inertia moderate for responsive motion.
The rotor is balanced to a standard grade, reducing vibration at its nominal speed of 6000 rpm. A centering diameter of 95 mm aligns the flange accurately to adjoining machine components, and connections exit on the left side through a keyed connector that carries power and feedback lines. Continuous torque at standstill reaches 4.4 Nm. A standard housing protects the stator laminations, and an internal blocking brake is fitted to secure the shaft when power is removed. Rear-mounted feedback electronics transmit rotor position data to the drive, enabling closed-loop current and velocity regulation.
The integrated brake supplies 3.0 Nm of static holding torque, so vertical axes can remain locked without external clamps. Position data are reported through digital servo feedback, allowing fine interpolation across the speed range and supporting accurate commutation during reversing motion. The output uses a plain shaft with a shaft seal to help limit dust or coolant ingress, and there is no secondary side B shaft extension. This shaft arrangement simplifies installation in couplings or gearboxes and keeps the drive end easy to align during assembly. The sealed shaft end is suitable for installations where light contamination may be present around the machine interface.
