Product Description:

The MKD112B-058-GP1-BN is a servo motor manufactured by Bosch Rexroth Indramat within the MKD Synchronous Motors series. It uses the 112 frame size and B length class, giving it a medium-inertia profile suited for packaging, transfer, and indexing equipment. Brushless motor construction and integrated feedback allow the unit to convert commanded current into tightly regulated torque for closed-loop motion in automated production lines. This operating profile suits axes that must accelerate predictably, reverse direction often, and maintain stable speed under changing process loads.

The motor mates to machinery through a centering collar of 130 mm and a square flange measuring 192 mm. This mounting geometry helps the motor sit squarely against machine plates and supports accurate shaft alignment with couplings or gearboxes. Torque is transmitted through a keyed shaft, and a front shaft seal helps protect the bearing from contaminants during operation. Cable hardware is positioned on Side B, and the housing carries a continuous standstill torque rating of 28.0 Nm for sustained holding duty. Rotor position is returned to the drive by resolver feedback, which supports stable control during speed and position changes.

An integrated holding brake supplies 22 Nm of static torque, allowing gravity or process loads to remain fixed when power is removed. Power, brake, and feedback conductors exit through a single output connector, which keeps cable routing compact at the motor housing and reduces the number of separate cable entry points. The motor uses winding code 058, and position detection is relative, so the controller performs a reference move after startup before absolute coordinates are established. This arrangement is well suited to medium-duty axes that cycle frequently and require repeatable positioning after each homing sequence.
