SY-WMVS-22 is a single-phase variable speed induction motor manufactured by SPG Korea for marine HVAC damper actuators. Rated at 120W 220V 60Hz with adjustable speed from 90 to 1700 RPM, it adopts Class F high-temperature insulation and built-in thermal overload protection to avoid winding burnout under stall or overloading conditions. The square flange mounting design facilitates installation on ship air dampers and ventilation valves, while the integrated cooling fan cover ensures stable heat dissipation in hot engine room environments. Multi-color lead wires simplify wiring with speed control units. Widely used as original spare parts for marine cabin air volume and temperature adjustment systems.
