Product Description:

The MKD112B-058-GG1-AN is a servo motor from the MKD Synchronous Motors series produced by Bosch Rexroth Indramat. In automated assembly lines and material-handling systems, the motor converts inverter output into accurately regulated rotary motion for coordinated axis control. An integral electromagnetic brake locks the shaft when supply power is absent, which helps hold suspended or driven loads in place during stops. This arrangement suits axes that need repeatable motion during operation and dependable holding when power is removed.

Its mechanical interface uses a 192 mm flange with a 130 mm centering diameter, providing a rigid seat against gearboxes or machine frames while maintaining concentric alignment. Cables exit on Side A, and the output connector keeps the electrical connection at one end of the housing for straightforward routing. The motor delivers a continuous standstill torque of 28.0 Nm, allowing the drive to maintain holding force at zero speed without excessive heat buildup in normal operation. The integrated brake applies 22 Nm to hold the shaft during downtime, which is useful when an axis must remain fixed after motion stops. Closed-loop control relies on resolver feedback (RSF), which sends analog sine-cosine signals to the drive for commutation and position evaluation.

The motor uses a plain shaft, which supports coupling methods that rely on clamping or other friction-based hub connections. A shaft seal helps protect the front bearing area from dust and coolant splash in industrial environments. Electrical behavior follows winding code 058, so the matching drive must use motor data that corresponds to this winding. The frame configuration is motor size 112 with motor length B, giving the unit a mid-range mechanical envelope for servo axes. Because the position signal is relative, the control system performs a homing move before the machine can run fully coordinated motion sequences.
