Product Description:

The MKD112B-058-GP0-AN is a servo motor produced by Bosch Rexroth Indramat and belongs to the MKD Synchronous Motors series. Within automated assembly lines, packaging cells, and material-handling stations, it converts drive-inverter output into rotational motion that can be tightly regulated for position, speed, and torque demands. This operating profile suits axes that require repeatable motion during indexing, transfer, and synchronized machine movements. The motor is intended for closed-loop operation with a matching drive, allowing controlled acceleration and steady running under changing loads.

A centering diameter of 130 mm aligns the stator housing with machine flanges, and the front mounting face carries a 192 mm square flange for direct attachment to standardized adapter plates. The rotor can deliver a continuous standstill torque of 28.0 Nm, which provides holding force for indexing tables without overheating. Cabling exits on Side A through a sealed output connector, which helps simplify wiring in compact cabinets. Motion feedback relies on resolver feedback (RSF), allowing the drive to detect relative rotor position with high noise immunity. Resolver-based feedback is useful where stable position sensing is needed in electrically noisy industrial environments.

The unit ships without a holding brake, so axis locking must be managed by the drive or by external clamping devices. Power is transmitted through a shaft with keyway, enabling keyed couplings to resist slip under cyclic torque. A shaft seal is installed to block dust and coolant from the bearing cavity in fluid-rich environments. Winding code 058 identifies the electrical winding used with MKD-compatible inverters. The motor also uses size 112 with B length, which places it in a mid-length housing for this frame. This arrangement supports installations where positive torque transfer and protection against contamination are both required.
