Product Description:

The MKD071B-061-FG0-KN is a servo motor manufactured by Bosch Rexroth Indramat for the MKD Synchronous Motors series. It converts drive-controller output into precisely regulated mechanical motion for positioning axes, feeders, and other automated machine functions on the factory floor. The motor is intended for closed-loop applications where stable torque and accurate shaft response are required during both movement and controlled standstill. Its synchronous design supports repeatable operation in machinery that depends on consistent positioning over long duty cycles.

This model sustains a continuous torque of 8.0 Nm at standstill, so the shaft can hold load without overheating when motion is paused. A 115 mm square flange aligns the housing with standard IEC mounting faces, and a centering diameter of 95 mm keeps the motor concentric with the driven mechanics. Winding code 061 matches the stator’s electrical characteristics to a compatible drive for proper current regulation. All terminations are routed through a sealed connection box, and the enclosure has an IP65 rating that resists dust entry and water jets in typical cabinet-free installations. The motor is supplied without a holding brake, so static load retention must rely on servo torque or an external mechanical device.

The shaft is a plain shaft with no keyway, allowing force-fit couplings to clamp anywhere along the journal. Power and feedback leads exit on Side B, which can simplify cable routing in right-hand machine layouts. The windings use F class insulation, allowing internal temperatures up to 155 °C under cyclical loading. Operation is permitted in ambient air from 0–40 °C; outside this range, derating or enclosure conditioning is required. A shaft seal helps prevent lubricant migration into the stator cavity, and the size 071 frame with the B-length stator stack keeps the overall package compact for tight installation spaces.
