The power quality may not meet the demand, because off-grid units are generally not as stable as the large power grid, and there may be problems with power frequency and voltage fluctuations. If batteries are used to store energy, the cost is relatively high, and it is unlikely for ordinary households to invest. This is The problem that is currently difficult to solve is that if it is a grid-connected wind turbine, a relatively large grid access system is required. In short, the investment is very large.
After the hub motor of an electric bicycle is converted into a wind turbine, its power generation efficiency does have a certain relationship with the power of the motor. However, it should be noted that this relationship is not simply proportional. In theory, the potential power generation capacity of a larger motor may be higher after being converted into a generator, because high-power motors usually have stronger magnetic fields and current handling capabilities. However, the actual generated power is also affected by many factors such as wind conditions, generator design, and conversion efficiency.
As for the difference between 12v and 48v motors after being converted into generators, they are mainly reflected in the following aspects:
1. Output voltage
A generator converted from a 12v motor will primarily output 12v or close to it under ideal conditions, while a 48v motor may output a higher voltage. However, it is important to note that the output voltage is not constant and fluctuates as wind conditions change.
2. Current handling capacity
Due to differences in design, the current handling capacity of the 48v motor may be stronger, so it may Has higher power generation potential. But this also depends on the specific motor design and modification options.
3. Application scenarios
Generators with different voltages are suitable for different application scenarios. For example, a 12v generator may be better suited for powering low-voltage equipment, while a 48v generator may be better suited for powering equipment requiring higher voltage.
Converting the hub motor of an electric bicycle into a wind turbine is a complex process, involving knowledge in multiple fields such as motor design, power electronics, and wind energy conversion. In actual operation, it is recommended to seek professional help to ensure the safety and effectiveness of modification. At the same time, since the modified generator may not be able to achieve the efficiency and performance of the original motor, its actual performance and limitations need to be fully considered when using it.
