The shaft is a keyway type, and the housing is rated IP65 — sealed against washdown and dust ingress, suitable for machine-tool spindles, packaging lines, and food-grade equipment where coolant or cleaning spray is present. The 0.75 kW rating at 200 V AC supply defines the continuous power the motor can deliver without overheating. The 2.4 Nm rated torque is what it holds continuously at rated speed; the 8.4 Nm peak torque (roughly 3.5× rated) handles acceleration and short-duration overloads — typical for indexing or cutting cycles. The 3000 rpm rated speed is the base speed for full torque; above that, the motor enters constant-power field-weakening up to 6000 rpm.","metaTitle":"Mitsubishi HG-KR73K MELSERVO-J4 Servo Motor, 0.75 kW, 2.4 Nm","metaDescription":"Mitsubishi HG-KR73K MELSERVO-J4 servo motor, 0.75 kW rated, 2.4 Nm / 8.4 Nm peak torque, 3000/6000 rpm, 4M resolution encoder, IP65, keyway shaft.
