First determine the power and supply voltage of the fan. Because some large-scale fans are very powerful and require super-large motors, such as 10,000V voltage, the domestic fan series is basically complete. You can find the required motor, and then design the power distribution system according to the rated voltage of the motor.
The rated voltage is the optimal voltage for an electrical appliance to work for a long time. In layman’s terms, it is the voltage value at both ends when the electrical appliance is working normally (such as the light bulb lighting up normally, the motor running normally, etc.). If it is too high, it will easily burn. Bad, low and abnormal operation (the light bulb does not light properly, the motor does not operate normally).
When electrical equipment works continuously for a long time, the current when the stable temperature reaches the maximum allowable temperature becomes the rated current of the equipment

In a DC circuit, the product of the rated voltage and the rated current is the rated power of the electrical appliance. Therefore, the rated voltage of the 50W wind turbine is 14/28v and the rated power is 0.05w. It does not mean that it can only drive the rated power of 0.05w. The voltage of electrical appliances is not only 14/28v
