Product Description:

The MKD112B-058-KG0-AN is a servo motor produced by Bosch Rexroth Indramat for the MKD Synchronous Motors series. Designed for closed-loop industrial automation, the unit converts drive controller current into rotary motion for positioning and process tasks that require repeatable speed and stable torque. With resolver-based feedback integrated into the frame, it supports real-time regulation and helps the drive maintain accurate motion during load changes. The motor is intended to work directly with compatible Indramat digital drives in coordinated multi-axis systems.

The motor mounts with a centering collar diameter of 130 mm and a square flange that measures 192 mm on each side, allowing it to fit machine interfaces built for the MKD112 frame. A plain output shaft rated for a continuous standstill torque of 28.0 Nm can carry static load while using a simple coupling arrangement. Power and feedback leads exit on Side A through an output connector, which helps keep cable routing organized when space around the driven load is limited. The electrical behavior is matched by winding code 058, and motor length code B keeps the housing shorter where axial clearance is restricted. This combination suits installations that need the larger 112 frame without adding unnecessary motor length.

The rotor uses resolver feedback with absolute position over more than 4096 revolutions, so the controller can retain position information after power is restored. The motor is supplied without a holding brake, which means a vertical or suspended load must be secured by external braking or drive torque when the axis is stopped. The plain shaft supports direct coupling to gearboxes or machine loads without a keyed output profile. A shaft seal is installed at the front end to protect the bearing area from lubricant splash and airborne debris. The 112 frame with B length gives the motor moderate inertia, which helps balance acceleration response and mechanical stability on general-purpose servo axes.
