Product Description:

The MKD041B-144-FG0-KN is a servo motor produced by Bosch Rexroth Indramat within the MKD Synchronous Motors series. As a compact drive element for industrial automation, it converts drive current into precise rotary motion for positioning, packaging, and material-handling axes. The motor uses size 041 with B length, so the housing stays short while still using winding code 144 for its electrical characteristics. That format supports installations where the motor must fit inside narrow machine frames or behind guarding panels. The short housing also limits how far the unit projects beyond a mounting surface, which helps in dense assemblies.

The motor uses a centering diameter of 50 mm and a flange pitch circle of 82 mm, which help align the stator on gearboxes or mounting plates and maintain concentricity during acceleration. This mounting pattern supports accurate face mounting and stable shaft alignment during repeated motion cycles. A continuous standstill torque of 2.7 Nm allows the axis to hold load at zero speed while the servo drive supplies rated current. The housing is sealed to IP65, and a shaft seal helps keep dust and low-pressure water away from internal parts. Because the unit is supplied without a holding brake, any static load must be secured by external clamping or maintained electrically. The plain shaft transfers torque through frictional couplings and avoids keys that can introduce backlash.

Connections exit on Side B through a connection box, which can simplify cable routing when the drive amplifier is mounted below the motor. The connection box encloses the terminations and keeps the wiring point accessible on one face of the housing. Windings insulated to class F tolerate elevated operating temperatures during rapid duty cycles and repeated start-stop operation. The motor can operate in ambient air from 0–40 °C without derating. This temperature range suits enclosed industrial spaces where surrounding air remains controlled during normal production.
