Product Description:

The MKD112B-058-KP0-BN is a servo motor produced by Bosch Rexroth Indramat for the MKD Synchronous Motors series. It occupies motor size 112 and uses length designation B, placing it in the middle of the family’s torque range. Intended for industrial automation, the unit converts controlled stator currents from an Indramat drive into rotary motion that can synchronize packaging lines, material handling systems, or assembly stations.

The motor attaches to a machine frame through a flange with a diameter of 192 mm, and this dimension matches standard IEC mounting surfaces. The stator housing is precision ground to a centering diameter of 130 mm, so the motor seats concentrically against the mating pilot bore and minimizes radial misalignment. When energized at rated current, the rotor can deliver a continuous standstill torque of 28.0 Nm, giving the drive sufficient force for static holding or low-speed positioning. Torque is transmitted through a hardened steel shaft manufactured as a shaft with a keyway, which simplifies coupling to pulleys or gearboxes. Power and feedback reach the drive through an output connector, and all terminations face Side B for straightforward wiring.

Electrical and feedback characteristics describe how the MKD112B module integrates with a digital drive. The stator uses winding code 058, which matches the motor to drives that operate at medium line voltages. Rotor position is measured by a resolver feedback device that provides absolute data. Together with internal electronics, the system can report position over more than 4096 revolutions without losing its reference. Because the design is delivered without a holding brake, any vertical axis must rely on external mechanisms or dynamic motor torque for power-off retention. A shaft seal is fitted to reduce the chance of fluid ingress along the output shaft during washdown or coolant exposure.
