Product Description:

The MKD090B-058-KP0-KN servo motor is produced by Bosch Rexroth Indramat within the MKD Synchronous Motors series. As an electromechanical actuator for CNC cells, packaging lines, and general automation, the unit converts commanded current into controlled torque and speed so machine axes can position, index, or follow a velocity profile under closed-loop control. This operating role lets a matched drive regulate acceleration, holding behavior, and speed changes with consistent motion during repeated machine cycles.

The motor delivers a continuous standstill torque of 12.0 Nm, allowing it to hold loads for extended periods without thermal overload. A square flange of 140 mm mates to standard machine interfaces, and the centering diameter of 110 mm aligns the housing precisely on the mounting face. Cables exit on side B, keeping service loops clear of moving parts, while field wiring terminates inside a sealed connection box that provides strain relief and shielding. Integrated rotor angle measurement is handled by resolver feedback, supplying analog sine-cosine signals that the drive converts into position data. The 090 frame size places this model in the middle of the MKD range, making it suitable for medium-inertia axes that need stable and responsive motion.

Torque is transmitted through a shaft with a keyway, permitting secure coupling to pulleys or gearheads without relying only on friction fits. The assembly ships without a holding brake, so systems that need static load retention must use an external clamping device. Position information remains valid over absolute travel of more than 4096 revolutions, which lets the controller recover axis location after a power interruption without a homing cycle. An internal shaft seal helps limit coolant ingress, and the motor is well suited to palletizers, indexing tables, and print cylinders where steady torque and repeatable motion are important.
