The switch on your fan reverses the direction of rotation on your fan. So it can spin clockwise or counter clockwise. Why would you want to change the direction of your fan? It can do a lot to make you more comfortable in both the warm summer and the cool winter.
With a 3-speed motor, hot voltage is applied to the main winding at 3 different points. Only one point is fed at a time. This is what the fan switch does. When voltage is applied to each point, the main winding receives current as the voltage from the black hot wire completes the circuit with a white neutral wire.
In the summer, ceiling fans should rotate counterclockwise to push cool air down to the floor. The cool air evaporates perspiration and creates a wind chill effect, which makes you feel cooler without affecting the room temperature.
During summer months, your ceiling fan blades should be set to spin counterclockwise. When your ceiling fan spins quickly in this direction, it pushes air down and creates a cool breeze. This helps keep a room’s temperature consistent throughout the day and reduces the need for an air conditioner to run constantly.
If you are unsure if your fan is turning the correct direction, stand directly under the fan and look up. If the fan is moving counterclockwise and you feel a rush of air, it’s in the correct setting for summer. If you don’t feel much air movement, it’s possible that the fan is spinning in the wrong direction.
A ceiling fan direction switch or control adjusts the spin direction of a ceiling fan – clockwise or counterclockwise. Nearly all modern ceiling fans can be adjusted to rotate in the direction of your choice.
Electric fans have a motor that moves blades that are attached to a central rotating hub. … Electric fans have a motor that turns a shaft on which there is an impeller. The turning impeller creates air pressure, causing air flow. If the fan moves air in the same direction as its shaft, it is axial flow.
Fans blow air directionally, and take in air from behind them.
While most ceiling fans are remote control adaptable, meaning a remote can be added if desired, there are some of fans that come with a remote and cannot have a switch installed (i.e. remote only). Majority of fans include a wall switch (3 speed dial) that can be fitted into any standard switch plate.
The single most asked question in the whole course of that show was about the little black switch on the side of a ceiling fan. The simple answer is that it is to reverse the direction of the fan motor.
Most ceiling fans are designed to rotate clockwise and counter-clockwise. A clockwise direction draws cool air up and forces warm air down, which is great for winter or anytime you’re cold. A counterclockwise direction creates a downward airflow to cool you — that’s great for summer or anytime you’re hot.
Here’s what the switch actually does: Ceiling fans spin counterclockwise to push cool air downward, but some fans have a switch that spins the blades in the opposite direction to pull air upward and push the warm air that naturally rises back down. …
The working principle of fan is based on double field revoving theory. … So sparking is due to any fault in fan. But when you rotated it in opposite direction,its starting wind flux and running winding flux are opposes to each other. So winding of should damage or capacitor is expired.
Forward in the spring/summer: During the spring and summer months, you want your fan to spin forward in a counter-clockwise direction. This increases airflow by allowing the fan to push air down on you, causing a room to feel cooler than it really is.
The Reason For Two Directions
You can turn your thermostat up a little bit because you’ll feel cooler sitting under the breeze of a fan. Clockwise | In reverse (blades spinning clockwise), the blades create a subtle updraft, which pushes the warm air that naturally rises to the ceiling back down into the room.
A fan limit switch is a component of a furnace system that determines when the furnace blower assembly for hot air turns on and off. Essentially, this means that it determines when the hot air should be blown through your ventilation system.
