The HG-KR73K: The encoder is a 22-bit absolute/incremental type (4,194,304 p/rev), so it holds position on power loss and eliminates the need for a home return on startup. 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.
