Product Description:

The MKD090B-046-GP0-KN is a servo motor produced by Bosch Rexroth Indramat for the MKD Synchronous Motors series. As a rotary actuator in industrial automation, it converts drive current from a matched controller into controlled mechanical motion for positioning tasks on packaging lines, gantries, and material-handling stations. Its size code 090 and motor length B place it in a mid-range frame that balances installation space, rotor inertia, and available torque for general machine axes. This layout suits equipment that requires repeatable starts, stops, and short indexing moves during continuous operation.

A flange diameter of 140 mm aligns with gearboxes or direct mounts, while the centering pilot of 110 mm locates the housing concentrically to reduce runout during coupling. Power and feedback leads exit on Side B through a sealed connection box, which helps keep cable routing organized along the driven axis. The output shaft uses a shaft with keyway, so torque can be transferred through a standard keyed hub without a separate clamping element. Continuous torque at standstill is rated at 12.0 Nm, allowing the motor to hold load or index at low speed within its thermal range. An F-class insulation system supports winding temperatures up to 155 °C, and winding code 046 matches the electrical characteristics used by compatible MKD drive modules.

Feedback is supplied by a resolver feedback device that provides analog sine-cosine signals for relative positioning, and the control loop reaches a system accuracy of ±8 angular minutes after reference. Because the feedback is relative, the axis must be referenced before that positioning accuracy is available. An IP65 enclosure and a factory-installed shaft seal help keep out dust and low-pressure water jets, which supports use in dirty areas or washdown zones. The allowed ambient temperature of 0–40 °C maintains thermal margin during continuous duty, and the motor is supplied without a holding brake when passive load locking is not required.
