MDD041C-N-100-N2K-050MA0
The MDD041C-N-100-N2K-050MA0 is a brushless synchronous motor manufactured by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it serves as the mechanical output stage in compact positioning modules, pick-and-place axes, and small spindle drives. When paired with a compatible controller, the unit converts commanded current into rapid shaft rotation suited for tasks that demand tight velocity regulation at high cycle rates.
Mechanical fitment is guided by a centering diameter of 50 mm, allowing the motor flange to seat precisely against standard mounting faces with minimal runout. Continuous stall torque is rated at 2.05 Nm, which is the persistent load the rotor can support without overheating when airflow around the housing remains unobstructed. The rotor can reach a nominal speed of 10000 rpm, so the drive must support commutation frequencies suitable for that operating range. Electrical terminations exit on Side A, and the power and feedback bundle is delivered through a connector, which helps keep wiring compact. Position data is returned by resolver feedback, which provides single-turn angle information with good resistance to electrical noise. Dynamic balance of the rotating assembly is designated as standard, reducing vibration in lightly supported mechanisms.
Length code C indicates a mid-range stator body that balances thermal mass with space constraints in tight machine frames. A single shaft exit with a keyway enables direct coupling to pulleys or miniature gearboxes, while the opposite end remains closed in the standard shaft-end configuration. Because the motor is supplied without a holding brake and without a shaft seal, vertical loads require external locking and coolant splash requires external protection. The integrated feedback package includes an integrated absolute encoder, giving multi-turn position data for homing cycles that must survive power loss.
