Product Description:

The MKD071B-061-KP3-KN is a servo motor from Bosch Rexroth Indramat in the MKD Synchronous Motors series. It converts electrical energy into controlled rotary motion for positioning and speed control in automated machinery such as indexing tables and packaging lines. Motor size 071 and length code B place it in the medium-frame class, providing a balance between torque capability and envelope size. The model is supplied with a molded connection box that routes power and feedback leads into a sealed enclosure, supporting quick electrical hookup in confined machine frames.

It delivers a continuous standstill torque of 8.0 Nm, allowing an axis to hold load without external gearing while current remains within thermal limits. The mechanical interface follows a 115 mm flange pattern, so it mates directly with standardized gearboxes and mounting plates, and a 95 mm centering diameter keeps the motor concentric to the driven shaft to minimize runout. Rotor position is reported through resolver feedback with an integrated encoder, which produces sine-cosine signals that stay accurate in electrically noisy environments. The motor uses winding code 061, a coil set matched to 300 V class drives for predictable speed-torque curves.

All terminations exit on Side B, so power and sensor conductors are kept clear of the output shaft, and the sealed box simplifies cabinet wiring. The output shaft is machined with a shaft with a keyway, providing positive torque transmission through a keyed coupling instead of relying on friction alone. Multi-turn position detection is absolute for more than 4096 revolutions, letting the controller recover exact machine coordinates after power loss. An integrated holding brake clamps the rotor when disabled, and a fitted shaft seal keeps lubricant from migrating into the stator.
