Product Description:
The MKD071B-035-EG0-KN is a servo motor manufactured by Bosch Rexroth Indramat for the MKD Synchronous Motors series. Within automated machinery, this motor converts drive current from a compatible controller into controlled mechanical rotation for positioning, feeding, or indexing tasks on production lines. Its stator-rotor package is optimized for medium-frame axes where moderate torque and high positional accuracy are required, making it suitable for pick-and-place gantries, packaging stations, and light machining centers. When paired with the correct drive, it supports repeatable motion on axes that cycle frequently and need stable response during starts, stops, and short dwell periods. This makes it a practical choice for equipment that repeats the same motion path over long production runs without requiring a large motor frame.
A centering diameter of 95 mm seats the housing accurately in the machine frame and helps maintain alignment with the driven load. At standstill, the motor can deliver a continuous torque of 8.0 Nm, allowing it to hold loads during dwell periods without overheating. Power and feedback conductors leave the enclosure on side B, and the terminations are placed inside a sealed connection box for protected cable routing. This layout keeps the cable exit grouped to one side of the motor and can simplify routing in enclosed machine sections. The aluminum enclosure has an IP65 rating, and the plain shaft transfers motion directly to couplings or gear stages used on compact machine axes.
The mounting flange measures 115 mm, providing a standardized interface for brackets or gearheads that match the 071 frame size. Operation is permitted in ambient air from 0 to 40 °C, and insulation class F allows winding temperatures up to 155 °C under intermittent duty. Winding code 035 indicates the electrical values used with compatible MKD drives, while the B motor length keeps the overall package suited to medium-frame applications. A factory-installed shaft seal helps limit lubricant migration, and the motor comes without a holding brake, so position holding must be supplied by the drive or an external mechanism. The lack of an integrated brake also reduces moving mass, which can benefit applications that prioritize quick acceleration and deceleration.
