Product Description:

The MKD090B-047-GP1-KN-SA001 is a servo motor built by Bosch Rexroth Indramat and belongs to the MKD Synchronous Motors series. The housing follows motor size 090 with length code B, giving the frame a compact axial dimension that balances inertia against torque. Designed for closed-loop motion axes, the unit converts electrical energy into controlled rotary output for positioning, indexing, or speed regulation tasks in automated machinery. Within these environments, the motor supplies repeatable torque while feedback devices report rotor position to the drive, forming the basis of high-precision servo loops.

This model delivers a continuous standstill torque of 12.0 Nm, meaning it can hold a load steadily without overheating when stationary yet energized. The square mounting flange measures 140 mm on each side, setting the bolt pattern that mates with reducer housings or machine frames. Accurate alignment during installation is assisted by a centering pilot of 110 mm, which keeps the rotor axis concentric with driven components and limits runout. Electrical characteristics are governed by winding code 047, a coil design that fixes the voltage constant and rated current so drive sizing remains predictable. Mechanical power is transmitted through a shaft with keyway, allowing set-screw or shrink-fit couplings to lock rigidly against torsional shock.

Dynamic holding requirements are met by an integrated brake that exerts 11 Nm of static torque, preventing back-driving on vertical or oscillating loads when power is removed. All power, feedback, and brake conductors exit on side B through a molded connection box that protects terminals from coolant and debris. Rotor angle is monitored through resolver feedback, supplying position signals that remain resistant to electrical noise and high temperatures. To support washdown or dusty plants, a shaft seal blocks coolant splash and airborne particles from migrating along the output journal.
