MKD041B-144-KP1-KN-SA001
The MKD041B-144-KP1-KN-SA001 is a servo motor built by Bosch Rexroth Indramat for the MKD Synchronous Motors series. This permanently excited AC unit converts drive controller output into rotary motion for positioning, feed, and auxiliary axes in automated machinery. It is intended for machinery that requires steady torque response and accurate closed-loop control during synchronized motion. Its size 041 frame, length class B, and winding code 144 give it a compact footprint while matching the electrical and mechanical layout used within the MKD line. Because it is a synchronous design, the motor responds well in systems that require coordinated acceleration, controlled stopping, and repeatable motion over short or frequent cycles.
The motor mounts to a square flange with a centering diameter of 50 mm to maintain alignment with gearheads or machine plates. Power and feedback cabling exit on Side B through a sealed connection box, simplifying panel routing and protecting the internal resolver harness. Under continuous stall conditions, the rotor delivers 2.7 Nm. The square mounting face measures 82 mm across, and the shaft seal helps protect the bearing area from contamination during normal machine operation. This cable arrangement keeps connections enclosed at the motor housing and can reduce interference with nearby machine components.
An electromechanical brake rated at 2.2 Nm is fitted to lock the axis when the drive is disabled, allowing vertical loads to remain stationary without external clamps. Rotor angle is monitored by resolver feedback with an integrated encoder, and multi-turn tracking is possible because the system provides absolute position detection over more than 4096 revolutions. This allows startup without a homing move after power loss and supports repeatable restart behavior on indexing axes. The holding brake and absolute feedback are useful where the axis must retain position information between power cycles. The motor uses a keyed shaft so torque can be transferred directly into couplings.
