Product Description:

The MKD041B-144-GG0-KN is an AC synchronous servo motor produced by Bosch Rexroth Indramat as part of the MKD Synchronous Motors series. This brushless unit is intended for closed-loop motion axes in assembly lines, packaging machines, and other automated equipment that require repeatable positioning and speed control. When paired with a compatible drive controller, the motor converts commanded current into accurate mechanical rotation, enabling coordinated multi-axis operation across an industrial automation cell.

The motor develops a continuous standstill torque of 2.7 Nm, allowing small indexing tables or feeders to hold load without additional gearing. Its front flange spans 82 mm, while the stator housing centers on a 50 mm pilot, providing clearance for compact machine frames and helping maintain coaxial alignment with gearboxes. Winding code 144 indicates the stator’s resistance and inductance, so drive tuning remains consistent across identical units. Rotor position and speed are measured through resolver feedback (RSF), enabling analog sine-cosine signals that maintain commutation even during electrical noise or temperature drift.

All electrical terminations exit on side B of the housing and are protected inside a connection box, simplifying cable routing along linear modules. Torque is transferred through a plain shaft that avoids keyway stress and suits clamp couplings, and a shaft seal is fitted to help contain lubricant spray. The motor comes without a holding brake, so static holding force must be provided by the drive or external mechanics. Size code 041 and length code B indicate the active stack height, while the relative position detection method suits applications that home at power-up without requiring absolute multi-turn data.
