Product Description:

The MKD041B-143-KP1-KN is a servo motor built by Bosch Rexroth Indramat within the MKD Synchronous Motors series. As a permanent-magnet AC unit, it supplies controlled rotary motion for positioning and velocity loops in automated machinery. The motor is suited for compact drive systems that require continuous-duty operation and closed-loop feedback for packaging lines, handling gantries, and other factory automation equipment.

During steady operation, the motor delivers a continuous standstill torque of 2.7 Nm, which allows small loads to remain energized without exceeding the thermal capability of its F-class insulation. Rotor position is measured through resolver feedback, so the drive can commutate accurately and maintain stable motion control during operation. The square mounting interface uses an 82 mm flange pattern, and a holding brake rated at 2.2 Nm secures the shaft when power is removed. The motor and connection box have an IP65 rating, and the installed shaft seal helps block dust and low-pressure water jets during machine use.

Mechanical alignment is supported by a 50 mm centering diameter, which helps locate the frame concentrically in gearheads or adapter plates. Electrical power and feedback cables exit on side B through a sealed connection box, which supports orderly cable routing along fixed machine structures. The motor maintains rated performance in ambient temperatures from 0–40 °C, and operation outside that range requires derating or additional cooling. Within the size-041, length-B housing, the keyed shaft supports repeatable alignment within ±8 angular minutes. The winding code 143 identifies the electrical winding arrangement used with compatible drive modules for the required current and voltage.
