Is there a relationship between power generation efficiency and motor power when the hub motor of electric bicycle is converted into a wind generator?

After the hub motor of electric bicycle is converted into a wind generator, its power generation efficiency is really related to the motor power. However, it should be noted that this relationship is not a simple proportional relationship. Theoretically, after the high-power motor is converted into a generator, the potential power generation capacity may be higher, because the high-power motor usually has stronger magnetic field and current handling capacity. However, the actual power generation is also affected by wind conditions, generator design, conversion efficiency and other factors.

As for the differences between 12v and 48v motors converted into generators, they are mainly reflected in the following aspects:

1, output voltage

The generator modified by 12v motor mainly outputs the voltage of 12v or close, while the 48v motor may output a higher voltage. However, it should be noted that the output voltage is not constant, and it will fluctuate with the change of wind conditions.

2. Current processing capacity

Because of different designs, 48v motor may have stronger current handling ability, so it may have higher power generation potential under strong wind conditions. But it also depends on the specific motor design and transformation scheme.

3. Application scenarios

Generators with different voltages are suitable for different application scenarios. For example, 12v generator may be more suitable for supplying power to low-voltage equipment, while 48v generator may be more suitable for supplying power to equipment requiring higher voltage.

It is a complex process to transform the hub motor of electric bicycle into a wind generator, which involves knowledge in many fields such as motor design, power electronics, wind energy conversion and so on. In practice, it is suggested to seek the help of professionals to ensure the safety and effectiveness of the modification. At the same time, because the reformed generator may not reach the efficiency and performance of the original motor, its actual performance and limitations should be fully considered when using it.
