Product Description:

The MKD112B-058-KG0-BN is a servo motor manufactured by Bosch Rexroth Indramat for the MKD Synchronous Motors series. Within an automation cell, it translates drive current into repeatable shaft rotation for precise indexing, speed regulation, and coordinated multi-axis movement. Its integrated feedback electronics and matched winding data allow it to operate with compatible digital drives in closed-loop motion systems. This makes the motor suitable for assembly stations, transfer lines, and machine tools that require stable response during changing load conditions.

A centering pilot of 130 mm aligns the flange and helps keep shaft runout low after installation. The square mounting pattern spans 192 mm, providing a fixed interface for machine attachment. Rated static output is 28.0 Nm, allowing the driven axis to sustain load torque at zero speed without excessive thermal stress. Power and feedback conductors exit on Side B through an industrial output connector, which can simplify cable routing away from the working face of the machine. Rotor position is monitored by resolver feedback mounted behind the shaft, supplying sinusoidal signals that let the drive calculate angle and velocity continuously during operation.

The motor is built without a holding brake, so parked loads must be secured by drive torque or an external mechanical restraint when power is removed. The drive end uses a plain shaft, and a shaft seal helps keep lubricant splash and airborne debris away from the bearing cavity. Winding code 058 corresponds to the electrical and thermal values expected by compatible Indramat drives. Absolute position detection beyond 4,096 revolutions supports startup without a homing move, while the size 112 stator and B-length housing provide enough active material for continuous operation in typical factory ambient conditions.
