Product Description:

The MDD071C-N-040-N2T-095GB2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded current into precise rotation for indexing tables, feeders, and assembly axes in automated production lines. The unit follows size 071 with length code C, achieving a compact body while still keeping enough thermal mass for repetitive duty cycles. A standard housing shields the stator, and the power and feedback leads exit through a single connector, supporting quick cabinet assembly and routine service access. Its factory-machined shaft end is the standard version without a second extension on side B, so it fits couplings or pulleys in tight machine enclosures.

The motor delivers 6.6 Nm of continuous torque at standstill, which is suitable for mid-range clamps and light gantries. Closed-loop speed regulation reaches a 4000 rpm nominal speed, allowing high cycle counts without exceeding the magnetic core temperature. The flange aligns to a spindle or gearbox through the 95 mm centering diameter, which helps keep radial runout low. Position and speed information returns to the drive through Digital servo feedback (DSF) generated by the integrated multiturn absolute encoder; this combination removes the need for external homing switches and maintains absolute position after power loss or a controlled shutdown.

A blocking brake rated for 6.5 Nm holding brake torque prevents axis drift when the controller is disabled, making the motor suitable for vertical loads. The output side uses a plain shaft with a factory-installed shaft seal to keep lubricant from migrating into the stator area. Cables approach the unit from the rear because the terminals use a connection on side B, which simplifies routing in compact cabinets and crowded machine frames. Vibration during acceleration is limited by standard balancing, which helps maintain smooth running during repetitive motion.
