The HC-KFS73B is an AC brushless rotary servo motor from Mitsubishi Electric's MELSERVO J2S series. It is a compact and adaptable servo motor developed for various industrial applications such as robotics, CNC machines, and packaging-related applications. Its ability to respond swiftly to changes in input signals makes it ideal for applications needing rapid acceleration and deceleration. It is a small-capacity, low-inertia motor that provides precise and efficient motion control in low-inertia applications; the moment of inertia is 0. 0001635kg.m2 (1.635kg.cm2). The maximum output power of the HC-KFS73B servo motor is 750 Watts. It has a rated rotating speed of 3000 rev/min, a highest speed rating of 4500 rev/min, and an instantaneous allowable speed rating of 5175 rev/min. It has a nominal rated torque of 2.4 Nm (7.2 Nm maximum), a rated current of 5.8 amps, and a maximum current of 18.6 amps; it operates with 200 volts class AC power. The HC-KFS73B servo motor has an integrated electromagnetic brake, which improves its functionality and safety. This servo motor has a typical straight shaft layout, making it compatible with various mechanical systems. Its shaft lacks a shaft key and a keyway. This servo motor's IP55 ingress protection rating makes it appropriate for usage in harsh settings. It is safe from moderate debris, dust, and water levels in its surroundings. It is intended to be controlled by a Mitsubishi servo amplifier. The absolute/incremental encoder on this servo motor detects speed and position and has a resolution of 131072 pulses per revolution.
