The Mitsubishi HG-SN52J-S100 is a 0.5 kW servo motor from the HG-SN series, delivering 2.39 N·m rated torque at 2000 r/min, with a maximum speed of 3000 r/min and an instantaneous permissible speed of 3450 r/min. The IP67 totally enclosed, natural-cooled housing means it handles washdown environments — no external fan to clog, no path for coolant or dust into the windings. Rated current sits at 2.9 A, peaking at 9.0 A under load transients.
The 2.39 N·m rated torque at 2000 r/min suits direct-drive or low-ratio belt-coupled indexing axes in packaging, material handling, or assembly cells. The 15:1 recommended load-to-motor inertia ratio is the practical limit for stable tuning without a separate load observer — exceed that and you are fighting resonance in the position loop. IP67 and the V10 vibration rank (low vibration, balanced to grade R) mean it mounts on a machine frame without soft mounts and survives coolant spray. Ambient operating range is 0 °C to 40 °C, non-condensing; storage down to -15 °C is fine for unpowered spares in a conditioned store.
