Product Description:

The MKD090B-035-KG2-KN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MKD Synchronous Motors series. It serves as a rotary actuator that converts drive current from a compatible controller into precise mechanical motion for axes that require closed-loop speed and position regulation in industrial automation cells. In normal operation, the motor supports repeatable motion on feed axes, indexing systems, and other equipment where stable torque output and accurate feedback are needed throughout the duty cycle.

This motor delivers a continuous standstill torque of 12.0 Nm, allowing it to hold or slowly index a load without overheating during prolonged dwell periods. A centering diameter of 110 mm aligns the housing to gearboxes or machine frames, while the 140 mm square flange provides a rigid mounting face. Size code 090 with length code B indicates a medium body depth for this motor frame. Power and feedback leads exit on Side B, and terminations are made through a connection box that simplifies cable routing and access. Rotor position is monitored by a resolver feedback device integrated with the shaft, and the electronics support absolute position sensing beyond 4096 revolutions so the axis can retain position information after power is restored.

The mechanical interface uses a plain shaft that fits standard clamp couplings and helps keep backlash low at the connection point. A shaft seal surrounds this journal to limit the ingress of coolant spray or dust when the motor is installed in enclosed machinery. The electromagnetic circuit uses the 035 winding code, which matches the motor to drive amplifiers that deliver the appropriate current and voltage characteristics. This arrangement is suitable for packaging machines, transfer lines, and material-handling equipment that require consistent servo response during repeated starts, stops, and positioning moves.
