Product Description:

The MKD041B-144-GG0-KS is a servo motor produced by Bosch Rexroth Indramat within the MKD Synchronous Motors series. As a rotary actuator, it supplies closed-loop torque and position control to indexing tables, pick-and-place axes, and other automated stations that require precise velocity regulation. Its integration with digital drive controllers allows coordinated multi-axis motion without added gearing or clutches. That makes it suitable for compact automation cells where repeatable starts, stops, and short positioning moves are common.

This motor delivers a continuous standstill torque of 2.7 Nm, allowing steady thrust on low-speed loads without overheating. The mechanical interface uses an 82 mm square flange and a 50 mm centering diameter, so it mounts directly to compact gearboxes or machine frames. The housing is sealed to IP65, which helps protect the windings from dust and water jets. Rotor angle is detected through resolver feedback, providing analog sine-cosine signals for commutation at low speeds. Power and feedback leads exit on Side B through a rear-facing connection box, which can simplify cable routing when the motor nose faces the work area. The motor uses size code 041 and length code B, which indicate the stator stack height.

Position repeatability is rated at ±8 angular minutes, which suits medium-accuracy assembly equipment. The motor operates in ambient temperatures from 0–40 °C without thermal derating, and its F-class insulation system tolerates winding temperatures up to 155 °C. A plain shaft is fitted with a shaft seal to help prevent oil migration while maintaining concentricity. This arrangement supports clean operation where lubricant migration could affect nearby components. Winding code 144 matches the stator copper to drives that supply the required voltage constant. Position detection remains relative, and the unit is supplied without a holding brake, so static load retention must be handled by external mechanics or by the drive’s torque-holding capability.
