Product Description:

The MKD112B-048-GP1-AN is a servo motor produced by Bosch Rexroth Indramat within the MKD Synchronous Motors series. It is intended for electrically driven axes where closed-loop velocity and position control are required, allowing machine tools, handling modules, and packaging lines to convert drive current into precise rotary motion. When connected to a compatible controller, the motor supports accurate acceleration, positioning, and repeatable speed regulation during cyclic machine operation. Its synchronous design also helps the drive maintain stable motion during frequent starts, stops, and reversals.

Mechanical interfacing starts with a centering diameter of 130 mm that aligns the housing to the mounting surface, while the square flange spans 192 mm on each side for four-bolt attachment. This mounting arrangement supports accurate alignment between the motor and connected machine components, which helps reduce unnecessary stress on the shaft and bearings. Motor cabling exits on Side A through an output connector, which helps keep the cable path clear of adjacent machine elements. Under continuous excitation, the rotor can deliver 28.0 Nm at standstill, allowing the axis to maintain torque during zero-speed operation. Speed and commutation data come from resolver feedback (RSF), which returns analog sine-cosine signals to the drive controller for vector calculation. Because the resolver reference is re-established at power-up, the system can recover relative position after startup without requiring absolute multi-turn memory.

An integrated holding brake clamps the rotor when power is cut, producing 22 Nm so vertical axes do not drift. Torque is transmitted through a shaft with a keyway, which mates with keyed couplings for positive power transfer. A shaft seal is present to help block oil or coolant ingress, and the internal sealing supports use around industrial machine processes. The brake supports load retention during power loss or controlled stops, while the keyed shaft provides a straightforward mechanical interface for couplings, pulleys, or gearbox inputs. Frame code 112 gives the motor its installation size, and winding designation 048 matches the electrical characteristics expected by compatible drive units.
