Product Description:
The MKD112A-058-KG1-BN is a servo motor built by Bosch Rexroth Indramat for the MKD Synchronous Motors series. In an automated cell, it converts drive current into controlled mechanical motion for positioning tables, gantries, and packaging axes that rely on resolver feedback for closed-loop control. Its resolver-based feedback system provides absolute position data over more than 4096 revolutions, allowing the controller to recover axis location immediately after power cycles and keep coordinated motion accurate across multi-axis assemblies. This arrangement supports repeatable starts, consistent synchronization with other axes, and stable speed regulation during frequent indexing or reversing moves.
A centering diameter of 130 mm aligns the housing with matching machine frames, while the flange dimension of 192 mm follows standard motor-mount patterns so the size 112 stator fits common servo plates. Wiring exits on Side B through a sealed output connector, which helps keep cables clear of adjacent mechanics and reduces interference with nearby guards, slides, or couplings. Continuous stall capability reaches 15.0 Nm, so the shaft can hold that torque continuously within its thermal limits during loaded dwell periods, and the motor has an IP65 enclosure rating that protects the housing, connections, and internal windings from dust and low-pressure water jets often present inside industrial enclosures.
A normally engaged holding brake supplies 22 Nm, so vertical or indexing axes remain locked when the drive is disabled and do not drift under static load. Insulation class F allows winding temperatures up to 155 °C without damaging the varnish system, and system precision is held within ±8 angular minutes, supported by fine feedback interpolation and a shaft seal that helps keep oil vapor away from the feedback cavity. Operation is permitted in ambient temperatures from 0–40 °C, and the plain shaft with an output connector keeps installation straightforward where a keyed shaft or fixed cable entry is not required.
