Product Description:
The MKD090B-085-KP0-AN servo motor is manufactured by Bosch Rexroth Indramat and belongs to the MKD Synchronous Motors series. It is a brushless AC unit intended for closed-loop motion axes in machine tools, assembly stations, and material-handling gantries where repeatable torque and speed regulation are necessary for cycle-time consistency and accurate axis synchronization. As a servo motor, it converts electrical energy from a compatible drive into controlled rotary motion while providing real-time position data back to the controller for deterministic automation tasks during repeated positioning cycles. This arrangement allows the paired controller to correct speed and position errors as machine loads change during operation.
At standstill, this model can supply a continuous torque of 12.0 Nm, giving a reference for static load capacity before thermal limits are reached. Mechanical integration is guided by a centering diameter of 110 mm and a flange measuring 140 mm; these dimensions align with mounting interfaces and simplify alignment on gearboxes or adapter plates. All power and feedback terminations are routed on side A through an output connector for straightforward cable routing. Feedback is generated by a resolver feedback device inside the housing, and it returns position data to the drive for closed-loop control. Because it is delivered without a holding brake, any load-side position retention during power loss must be handled by external clamping devices or drive torque.
The motor has a sealed IP65 housing that blocks dust ingress and low-pressure water jets. Its B-length stator stack inside the size 090 frame balances inertia against torque for indexing tasks, and closed-loop accuracy is aided by a system precision of ±8 angular minutes. The motor can operate in ambient temperatures from 0 to 40 °C without derating, and it uses insulation class F windings. For torque transmission, the output shaft is machined as a shaft with keyway, ensuring slip-free coupling to pulleys or couplings while the integral shaft seal helps prevent lubricant migration along the journal. This shaft form is commonly used where the driven element must transmit torque without relying only on a friction clamp.
