Product Description:
The MKD112B-048-GG1-BN is a servo motor produced by Bosch Rexroth Indramat and belongs to the MKD Synchronous Motors series. It converts drive current from a compatible controller into controlled mechanical rotation for positioning and velocity tasks in industrial automation cells. In automated equipment, it is suited to feed axes, rotary tables, and transfer mechanisms that require repeatable motion. Closed-loop operation allows the connected drive to correct for changing loads and maintain commanded speed or position through the operating cycle.
At installation, the housing mates with a centering pilot of 130 mm, while a flange square of 192 mm sets the bolt pattern for rigid coupling to the machine frame. During continuous stall, the electromagnetic system can deliver 28.0 Nm of torque, giving the axis solid low-speed holding capability without extra gearing. Position feedback is obtained through resolver feedback, which returns analog sine-cosine signals so the controller can compute rotor angle during acceleration and normal running. Power and feedback conductors exit through an output connector, which streamlines cable replacement and helps seal the electronics from ambient oil and dust. This arrangement also keeps the electrical interface compact and supports orderly cable routing at the motor.
The electrical junctions are oriented toward side B, allowing cable routing away from moving parts. A permanently engaged brake provides 22 Nm of holding torque so suspended or vertical loads stay fixed when power is removed. The rotor has a plain shaft, which facilitates direct coupling with clamping hubs or clamp collars, and a factory-installed shaft seal blocks coolant or cutting fluid from migrating into the front bearing. Winding designation 048 identifies the resistance and inductance set used for drives that operate this 112-frame, length-B motor and support efficient current use across its speed range.
