Product Description:

The MKD112B-048-GG2-AN is a servo motor built by Bosch Rexroth Indramat and assigned to the MKD Synchronous Motors series. It is intended for closed-loop axis control in machine tools, packaging lines, and automated assembly stations, where it converts regulated drive currents into precise rotary displacement at commanded angles. As part of a digital drive system, the motor exchanges real-time position data with the controller, allowing commanded profiles in position, velocity, and torque to be followed accurately. This feedback path helps the controller correct deviations caused by changing load conditions before position error becomes significant. The winding layout supports stable operation during repeated acceleration and deceleration cycles in continuous industrial use.

The motor supplies a continuous standstill torque of 28.0 Nm, allowing actuators to hold static loads without external brakes. Accurate mounting is aided by a centering diameter of 130 mm, while the flange conforms to a 192 mm square pattern that matches standard gearbox adapters. Rotor position is captured by a resolver feedback (RSF) element, which outputs analog sine-cosine signals for fine interpolation in the drive controller. The sensor supports relative position detection, so homing is required after power-up. Power and feedback cabling exit on Side A, which can simplify cable routing when multiple axes are installed in series.

Despite the medium motor length B envelope, electrical termination is provided through an integrated output connector. Mechanical coupling uses a plain shaft, so torque is transmitted through a clamping hub or keyed hub without gear teeth. The frame, identified as Motor Size 112, pairs with the 048 winding to balance current demand and speed range in general-purpose servo loops. A shaft seal is installed to help protect the bearing area from contaminants during operation.
