The 5.8 A rated current is the continuous thermal limit at the nameplate torque; the 18.6 A maximum current is the peak available for acceleration or short-duration overloads, typical for servo drives that supply 300–400% peak current. The 1.3 kVA power facility capacity tells you the drive-side transformer or supply must be sized for that apparent power draw, not just the 0.75 kW mechanical output. Maximum speed of 4500 r/min and a permissible instantaneous speed of 5175 r/min — the motor can overshoot briefly during deceleration or a fault condition; the drive's speed regulator should be tuned to keep transients below that hard limit to avoid mechanical damage or encoder over-speed. The power rate of 37.7 kW/s at continuous rated torque indicates how quickly the motor can accelerate a given inertia — useful for matching to load inertia in a sizing calculation.","metaTitle":"Mitsubishi HC-KFS73 Servo Motor, 0.75 kW, 3000 r/min, EOL","metaDescription":"Mitsubishi HC-KFS73 servo motor, 0.75 kW rated output, 5.8 A rated current, 3000 r/min.
