After the hub motor of an electric bicycle is converted into a wind turbine, its power generation efficiency has a certain relationship with the power of the motor. It should be noted, however, that this relationship is not simply proportional. In theory, the potential power generation capacity of a larger motor can be higher after being converted to a generator, because higher horsepower motors generally have stronger magnetic fields and current handling capabilities. However, the actual power generated 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 conversion into generators, they are mainly reflected in the following aspects:
1. Output Voltage
A generator converted from a 12V motor will primarily produce 12V or so under ideal conditions, while a 48V motor can produce a higher voltage. However, it is important to note that the output voltage is not constant and fluctuates with changes in wind conditions.
2. Current handling capacity
Due to design differences, the current handling capacity of 48V motor may be stronger, so it can have higher power. generation potential. But it also depends on the specific engine 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 to powering low voltage equipment, while a 48V generator may be better suited to powering equipment requiring higher voltage.
The conversion of mChanging the hub motor of an electric bicycle into a wind turbine is a complex process, involving knowledge in multiple areas 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 the modification. At the same time, since the modified generator may not be able to achieve the efficiency and performance of the original engine, its actual performance and limitations should be fully considered when using it.
The electrical energy generated by each rotation of the wind power generator is also different. For example, the most common 2MW direct drive wind power generator has sufficient and stable wind power. The motor can generate 2,000 degrees of electricity every 60 minutes.
It takes 3.5 secondsthe fan blades to rotate once, and 60 minutes is 3,600 seconds. Therefore, the electricity generated by the generator per second is 0.56 degrees, so the amount of electricity generated by the fan is. the wind power generator for each tower is The power generated is 0.56 × 3.5 seconds, or 1.94 kilowatt hours of electricity.
Detailed informationAs the wind volume is unstable, the wind turbine produces 13~25V alternating current, which needs to be rectified by the charger, and then charge the battery to produce the wind. power The electrical energy produced by the generator is converted into chemical energy. Then use an inverter with a protection circuit to convert the chemical energy of the battery into AC 220V mains power to ensure stable use.
Mechanical connection and power transmission: The horizontal axis fan blades are connected to the couplinguniversal elastic ent via the gearbox and its high speed shaft to transmit torque to the generator drive shaft. This coupling must have good damping and. vibration absorption properties.
Performed by absorbing the appropriate amount of radial, axial and some angular deviations, and the coupling can prevent overloading of the mechanical device. The other type is direct drive fan blades which are directly connected to the motor without going through the gearbox. Fan Motor Type
