Electric fans move by using a motor to spin blades. This creates a flow of air that cools you down.
Here's how it works:
- Electricity powers the motor: When you plug in an electric fan, electricity flows through the motor.
- The motor spins a shaft: The electricity creates a magnetic field that causes a shaft inside the motor to spin.
- The shaft is connected to the blades: The spinning shaft is connected to the blades, which then begin to rotate.
- The blades push air: The spinning blades create a force that pushes air, creating a breeze.
Types of Electric Fan Motors
There are two main types of motors used in electric fans:
- AC motors: These are the most common type of motor used in electric fans. They are powered by alternating current (AC) electricity.
- DC motors: These motors are powered by direct current (DC) electricity. They are often used in smaller, more portable fans.
How Fan Speed is Controlled
The speed of an electric fan is controlled by the amount of electricity flowing through the motor.
- More electricity = faster speed: The more electricity flowing through the motor, the faster the shaft spins, and the faster the blades rotate.
- Less electricity = slower speed: The less electricity flowing through the motor, the slower the shaft spins, and the slower the blades rotate.
Electric fans are a simple but effective way to cool down on hot days. They work by using a motor to spin blades, which creates a flow of air that cools you down.
