The 200 Watt fan coupling works by using an electromagnet to create a magnetic field. This magnetic field engages the fan clutch with the fan blades, causing the fan to rotate. When the engine is cold, the fan clutch is disengaged and the fan does not rotate. As the engine warms up, the temperature of the coolant in the engine increases. This causes the 200 Watt fan coupling to heat up and the electromagnet to create a stronger magnetic field. The stronger magnetic field engages the fan clutch with the fan blades more firmly, causing the fan to rotate at a faster speed.
The purpose of the 200 Watt fan coupling is to regulate the engine temperature by controlling the speed of the cooling fan. The fan coupling is designed to engage and disengage the fan clutch at the correct temperatures, ensuring that the engine does not overheat or become too cold. The fan coupling also helps to reduce noise and improve fuel efficiency by only engaging the fan when it is needed.
