Product Description:

The MKD041B-144-KP0-KN-SA001 is a servo motor built by Bosch Rexroth Indramat and belongs to the MKD Synchronous Motors series. Within an automated cell, the unit converts drive current from a compatible controller into controlled mechanical rotation for positioning, conveying, or tool-handling tasks. Its compact design includes integrated feedback so the drive can regulate speed and position in robots, packaging lines, and CNC axes. This makes the motor suitable for applications that require repeatable motion during frequent starts, stops, and direction changes.

A centering diameter of 50 mm mates the front flange to precision mounting surfaces and helps maintain concentric alignment with the load. Power and feedback cables exit on Side B, and the wiring terminates inside a connection box that helps protect the terminals from contamination. At standstill, the motor can deliver 2.7 Nm of continuous torque for light-to-medium indexing duty while remaining within its thermal range. Position data are supplied through resolver feedback, which sends analog sine-cosine signals to the drive for closed-loop control. The terminal arrangement also keeps external connections contained within the motor housing rather than leaving them exposed at the rear of the frame.

The unit is supplied without a holding brake, so static load retention must be provided by external mechanics or drive torque. Absolute detection across more than 4096 revolutions allows the controller to recover position after power-up without a homing cycle, which helps maintain axis reference after a controlled shutdown. Torque is transmitted through a shaft with a keyway, and winding code 144 matches the electrical characteristics expected by compatible drive modules. The motor length B and the shaft seal support use in enclosed machinery where compact installation and protected shaft entry are important.
