The Mitsubishi HG-KN23J-S100 is a low-inertia, small-capacity servo motor delivering 0.2 kW rated output with 0.64 N·m of rated torque at 3000 r/min. That torque curve suits light-duty positioning axes — pick-and-place, small conveyors, or indexing tables — where the load-to-motor inertia ratio stays at or below 15 times. The motor can spin up to 5000 r/min (instantaneous permissible speed 5750 r/min), so it handles short over-speed moves for cycle-time gains without oversizing the frame. Rated current draws 1.3 A; peak current reaches 3.9 A. That tells the drive engineer the amplifier must supply at least 3.9 A peak for acceleration and deceleration. Insulation class 130 (B) keeps the winding safe up to 130 °C hot-spot — standard for this power class, no derating needed in normal 40 °C ambient.
IP65 enclosure and installation environment
It can live on a washdown line or in a humid plant without a separate cover — but the shaft seal and connector must still be mated properly to maintain the rating. The oil seal (the 'J' in the model code) is installed, so it tolerates oil mist common in gearbox-coupled applications. Ambient temperature range is 0 °C to 40 °C operating, storage down to -15 °C. If the machine sits in an unheated warehouse overnight, the motor survives the freeze; just let it warm up before full-load running. Vibration resistance is 49 m/s² on X and Y axes — that's about 5 g, enough for most machine-mounted installations without a vibration isolator.
