The power consumption of an electric fan is related to the formation of the motor structure and the size of the specifications (blade diameter). The power consumption of a capacitor type electric fan of the same specification is smaller than that of a shield pole type. The efficiency of converting electrical energy into civilian energy for fans with the same motor structure is higher than that of fans with smaller specifications. However, in terms of total power consumption, the larger the specification, the more power is consumed. Therefore, it is necessary to choose a reasonable one according to household needs.

The main component of a floor fan is an AC motor, which means the motor is the heart of the floor fan. The working principle of a floor fan and an electric fan is the same: the energized coil rotates under force in a magnetic field. The form of energy conversion is that electrical energy is mainly converted into mechanical energy, and due to the resistance of the coil, it is inevitable that a portion of electrical energy needs to be converted into thermal energy.
