Its 5.8 A rated current and 18.6 A peak current tell you the continuous and short-term thermal limits — size the drive and cabling for the peak, not the average, if your cycle includes acceleration or reversing loads. The 1.3 kVA power facility rating gives a rough transformer or supply sizing benchmark for a single-axis cell. ## Where it fits — speed and torque profile Rated speed of 3000 r/min and permissible instantaneous speed of 5175 r/min tell you this motor is built for moderate-speed positioning or constant-torque applications — think conveyor drives, spindle indexing, or pick-and-place axes where you need acceleration headroom. The power rate at continuous rated torque (37.7 kW/s) gives a feel for how fast it can ramp torque; useful when comparing dynamic response against a larger-frame servo.","metaTitle":"Mitsubishi HC-KFS73B servo motor, 0.75 kW, 3000 r/min, EOL","metaDescription":"Mitsubishi HC-KFS73B servo motor, 0.75 kW rated output, 5.8 A rated current, 3000 r/min rated speed.
