MDD041A-N-100-N2K-050GA0
The MDD041A-N-100-N2K-050GA0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for digital drive controllers where compact, high-speed rotary motion is required for automated assembly stations, packaging spindles, or indexing tables. By pairing with a matched drive, the motor converts controlled current into precise angular displacement, allowing synchronized mechanical axes without the backlash associated with mechanical transmissions. Its electrical design supports closed-loop operation, so it can maintain repeatable cycles even under rapid load changes.
At the electrical level, the motor can deliver a continuous standstill torque of 0.64 Nm, sufficient for light pick-and-place grippers or small spindle loads while staying within thermal limits. Its rated mechanical speed reaches 10000 rpm, enabling fast cycle times when driven by a matched inverter. Power and feedback conductors exit on side A, and a removable connector simplifies cable installation. A centering pilot of 50 mm aligns the flange to adjoining machine frames. A factory-installed with a shaft seal arrangement keeps contaminants out of the bearings for reliable service in dusty areas.
The motor’s dynamic positioning accuracy is enhanced by resolver feedback, while an integrated absolute encoder retains rotor position after power loss and eliminates homing. The single plain shaft avoids keyway stress and mates with clamp couplings on low-inertia loads. Standard balancing holds vibration within ISO limits, and the standard housing with an A-length body shortens depth for dense multi-axis clusters. The unit is supplied without a blocking brake, so vertical axes require external holding devices when power is removed. The motor has a single shaft end, which reduces rotating mass and permits higher accelerations.
