MKD090B-047-6P6-KN
The MKD090B-047-6P6-KN is a permanent-magnet AC servo motor manufactured by Bosch Rexroth Indramat as part of the MKD Synchronous Motors series. The unit is designed for integration with drive controllers in automated production lines, where it converts electrical energy into tightly regulated rotational motion. By delivering responsive torque and repeatable speed control, the motor supports indexing tables, gantry axes, and other mechanisms that require accurate positioning under varying load conditions.
Its characteristic output begins with 12.0 Nm continuous torque at standstill, which is the torque the shaft can maintain indefinitely at standstill without overheating. Accurate mechanical alignment is aided by the 110 mm centering diameter, allowing the housing pilot to seat tightly in the mating machine frame. Mounting is completed through a square flange that measures 140 mm, establishing the bolt circle used to couple the motor to gearboxes or bearing blocks. The electromagnetic package belongs to motor size 090, a frame class that balances torque density and mass for medium-duty axes. Internal copper fill and insulation are identified by winding code 047, matching the stator to drives that supply the appropriate voltage constant and rated current.
The electrical terminals are located on the rear because the design uses a connection direction on side B, simplifying cable routing in cabinets where the shaft faces forward. Those conductors land inside a sealed connection box, which provides strain relief and shields the signal pairs from ambient interference. Axial length conforms to motor length code B, giving a compact footprint while still providing the stack height needed for this winding. A shaft with keyway transmits torque through positive mechanical engagement, and there is a shaft seal that blocks lubricant vapor and airborne contaminants from entering the bearing chamber during operation.
