Product Description:

The MKD112B-058-GG1-BN servo motor is manufactured by Bosch Rexroth Indramat and belongs to the MKD Synchronous Motors series. This rotary actuator converts drive-bus power into controlled mechanical rotation for positioning axes, feed drives, and automated handling stages within industrial automation cells. The integrated feedback and braking hardware allow the motor to function as a closed-loop prime mover that can start, stop, and hold loads with repeatable accuracy under a digital drive controller.

During continuous duty, the motor can deliver 28.0 Nm of torque while the rotor remains stationary, which sets the thermal load on the drive and the holding capacity before motion begins. A square 192 mm mounting flange matches standard machine interfaces, and the 130 mm centering diameter helps align the stator with gearboxes or couplings to minimize shaft runout. The electromagnetic circuit follows winding code 058, which sets phase resistance and inductance so the drive can apply correct current ramps. Motion feedback is supplied by resolver feedback (RSF), which outputs absolute sine-cosine signals for position and velocity loops even in high-vibration environments.

A power-off holding system provides 22 Nm of brake torque, allowing the axis to maintain position without external clamps when the controller is disabled. All power and feedback leads exit on Side B through an output connector, simplifying cabinet layout when multiple motors share a common cable track. Frame size 112 corresponds to a larger stator outside diameter and higher thermal mass than smaller MKD units, which helps during overload events without rapid temperature rise. A plain shaft, an integral shaft seal, and relative position detection complete the mechanical package while keeping the envelope short because of the B length code.
