Product Description:

The MKD090B-085-KG0-AN is a servo motor manufactured by Bosch Rexroth Indramat within the MKD Synchronous Motors series. As a brushless AC unit, it supplies controlled torque and speed for positioning axes, pick-and-place gantries, and packaging stations that require repeatable motion. Integrated electronic feedback and a direct-drive mechanical interface allow the motor to operate in closed-loop systems without separate external transducers. This arrangement supports precise speed regulation and stable positioning in automated equipment that runs through frequent start-and-stop cycles.

A centering diameter of 110 mm aligns the housing to the machine flange, while the power and signal leads exit on Side A through an output connector. This cable orientation helps keep routing compact and leaves more clearance around nearby mechanical parts. At stall, the motor can deliver 12.0 Nm of continuous torque for sustained load conditions. Position and velocity are measured by a resolver feedback device mounted with the rotor, and the square 140 mm flange supports rigid attachment to aluminum or steel structures. The combination of feedback and flange alignment helps the drive maintain accurate motion during repeated cycles.

The unit uses length code B, giving it a mid-frame body that balances thermal mass with installation space. A plain shaft transmits torque without keyways, which helps reduce eccentricity during high-speed operation. The motor also includes a shaft seal to help block coolant or lubricant ingress in washdown areas. Absolute position detection over multiple revolutions allows the axis to retain position information after power loss. Because the motor is supplied without a holding brake, vertical or suspended loads must be secured by the drive or by an external holding device.
