Product Description:

Bosch Rexroth Indramat manufactures the MKD071B-061-KP3-KS in its MKD Synchronous Motors series. As a compact servo motor, it pairs with Indramat digital drive controllers to execute repeatable velocity and torque profiles required for positioning tables, feed axes, and auxiliary drives in automated assembly and processing equipment. In closed-loop applications, it converts commanded current into controlled rotary motion so the connected axis can respond accurately to changing loads. The motor’s housing, feedback device, and mechanical interface are arranged to save control cabinet depth while still meeting typical industrial accuracy and environmental demands.

The unit delivers a continuous standstill torque of 8.0 Nm, allowing machinery to hold load without extra mechanical locks. A centering diameter of 95 mm aligns the stator to mating machine frames, and the square flange measures 115 mm for direct IEC-pattern mounting. Its enclosure carries an IP65 rating, giving full dust protection and tolerance to low-pressure water jets. Rotor position is monitored by a resolver feedback device that also supplies absolute data beyond 4,096 revolutions, supporting fine interpolation inside the drive. Power, brake, and sensor leads terminate in a sealed connection box located on side B of the stator, and a shaft seal helps prevent oil entry at the output coupling.

System accuracy is held within ±8 angular minutes, and the motor operates within 0–40 °C without derating. The output end uses a shaft with a keyway to transfer torque, and the windings are insulated to the Class F thermal limit. A factory-installed holding brake, sized to the frame, engages during power loss to secure vertical or inertial loads. Motor size 071, length code B, and winding code 061 identify the package and the matching electrical characteristics for this model.
