Product Description:
The MKD112B-048-GG2-BN is a servo motor produced by Bosch Rexroth Indramat for the MKD Synchronous Motors series. Within an automated cell, it delivers regulated torque and speed so that CNC tables, printing drums, or pick-and-place units follow commanded motion with low position error. The unit works with compatible digital drives to support closed-loop axis control during acceleration, steady running, and rapid positioning. Its housing format suits machines that use 112-frame motors for medium-power rotary axes and need a compact drive package with dependable feedback.
The motor supplies a continuous standstill torque of 28.0 Nm, allowing it to hold static loads without excessive heating under rated conditions. A centering diameter of 130 mm aligns the stator housing to the machine interface, while the 192 mm square flange provides a rigid mounting surface. Power and feedback cabling exit on Side B, and the single output connector keeps the connection point consolidated for cleaner routing through cable tracks or guarded machine spaces. This layout helps reduce cable clutter around the motor body and supports installations where access to the rear of the axis is limited. The mounting arrangement also helps keep shaft alignment stable when the motor is coupled to a gearbox, belt stage, or direct-driven load.
Rotor position is monitored by resolver feedback (RSF), which provides analog sine-cosine signals for closed-loop control. This feedback method allows the connected drive to track rotor angle continuously and maintain stable commutation during changing load conditions. The motor uses a plain shaft for torque transmission, and a shaft seal helps limit the entry or escape of contaminants and lubricant at the shaft outlet. The electromagnetic design uses winding code 048, which matches the motor to drives that supply the correct current and back-EMF range. Together with the sealed shaft end and resolver-based position sensing, the winding layout supports accurate speed regulation and repeatable motion in industrial servo applications.
