Working principle of AC fan motor

Nowadays, electric fans are often used in our daily lives. Using an electric fan can help us get through the hot summer and help us cool down during the summer. So, what is the working principle of an AC fan motor? Let's learn about it together.

Working principle of AC fan motor:

The main component of an electric fan is an AC fan motor. The working principle of an AC fan motor is that the energized coil rotates under the action of magnetic field force. Electrical energy is converted into mechanical energy, and inevitably, due to the resistance of the coil, a portion of the electrical energy will be converted into thermal energy. In addition, low-power motors, such as DC motors and DC brushless motors, are increasingly being used in small electric fans.

When the working principle of the AC fan motor (assuming there is no heat transfer between indoor and outdoor), the indoor temperature not only does not decrease, but also increases. Let's analyze the reason for the temperature rise: when the electric fan is working, this is because the current flowing through the coil of the electric fan has resistance, so it is inevitable that heat will be generated and released outward, and the temperature will naturally rise. But why do people think it's cool? Because there are many people's bodies, when the AC fan motor works, indoor air will flow, so it can promote the rapid evaporation of sweat. In addition, the evaporation of sweat on the body surface needs to absorb a large amount of heat, so people will feel cool.
