Product Description:
The MKD112B-048-KP1-AN servo motor is manufactured by Bosch Rexroth Indramat within the MKD Synchronous Motors series. As a brushless AC unit, it converts drive-controller commands into precise rotary motion for automated machinery that requires repeatable positioning. The motor combines integrated feedback with a holding brake, so it can support controlled motion during operation and help maintain axis position when power is removed. In typical installations, the paired drive uses the feedback channel to regulate speed and position as loads change. This arrangement suits conveyor sections, packaging stations, and other general motion axes in industrial automation.
A centering pilot of 130 mm aligns the housing concentrically with the machine plate, while the square flange spans 192 mm and establishes the bolt pattern for ISO-style attachment. The pilot and flange geometry help keep the shaft centered with the driven mechanism, which supports accurate coupling alignment. The motor delivers 28.0 Nm of continuous standstill torque, allowing stable force at zero speed without overheating. Power and feedback lines exit on side A, and a single output connector simplifies cable routing in compact cabinets. The housing uses size 112 with length code B, which sets the overall package dimensions.
The built-in holding brake supplies 22 Nm of static torque to secure the shaft during power loss, and the keyed shaft transfers torque through standard keyed couplings. Integrated electronics convert the resolver's sine-cosine signals into an absolute position value of more than 4096 revolutions, so the controller knows rotor angle immediately after startup. This resolver feedback also supports commutation without incremental homing cycles. The winding code is 048, which matches the thermal characteristics expected by compatible drive modules. A shaft seal helps curb grease migration and protect the internal bearings, and clean, filtered cabinet air supports normal cooling during operation.
