How can I get a generator with a small volume and high power?

No way, it's limited by the material.

To increase the power, you can increase the speed. But if you want to send 50Hz AC power, the maximum speed is 3000 rpm. There's no way to improve this.

It is possible to increase the current density of the wire. However, due to the influence of copper wire heating, this cannot be improved indefinitely. Or can you use silver as a wire? I heard that it has less resistivity. Or you can use superconductivity.

The strength of the magnetic field can be increased, but due to the limitation of the magnetic conductive silicon steel sheet, the magnetic field is large and the heat generation is large. Therefore, it is not possible to continue to improve.

Homemade high-power generator is a complex engineering project that first determines the required power output and voltage requirements, and designs the specifications and parameters of the generator according to these requirements.

Purchase or manufacture the required parts such as generator assemblies, bearings, coils, magnets, etc. Assemble the main structure of the generator, including the stator and rotor, according to the design specifications. The coil is wound around the stator to ensure the correct winding method and connection.

Attach the magnet to the rotor to ensure the correct polarity and position.

Connect the coils of the stator and rotor to the power supply and load to ensure proper electro-sensitive diversion layout and connection. The performance and stability of the generator are tested by gradually increasing the bridge voltage of the power supply and the power of the load. According to the test results, the parameters and structure of the generator are optimized and adjusted to achieve better performance and efficiency.

It should be noted that homemade high-power generators require professional knowledge and skills, and involve high-voltage and high-power circuits, so it is recommended to seek guidance and assistance from professionals to ensure safety and reliability.

Precautions for homemade generators

1. Safety: In the production process, pay attention to safety. Wear proper protective gear, such as gloves and goggles, when using tools to prevent accidental injury.

2. Material selection: choose materials suitable for making generators. Common materials include magnetic materials, copper wires, etc. Ensure that the material has good conductivity and wear resistance.

3. Magnetic field: When making a generator, pay attention to the way of generating the magnetic field. Common methods include the use of permanent magnets or the passage of electric current through a coil. Make sure the strength and direction of the magnetic field are correct.

4. Coil winding: The coil is an important part of the generator, and it is necessary to pay attention to the winding method and winding method of the coil. Ensure that the coil is wound tightly and evenly to improve power generation efficiency.

5. Current and voltage: When making a generator, the required current and voltage should be considered. Depending on the requirements of the equipment or battery used, select the appropriate coil and magnetic field strength to ensure that the generator is able to generate the required current and voltage.

The motor used for the fan can be converted into a generator. The rotor can be removed, the aluminum strip in the rotor and the aluminum short-circuit rings at both ends can be carefully removed, and the excitation winding can be added. Add slip ring, carbon brush and excitation circuit in series.

This method is cumbersome to operate, but the output voltage can be adjusted by magnetic adjustment.

Using an AC motor as a generator is called an AC asynchronous generator. The method of mating and using is very simple, just match the capacitor of the appropriate capacity on the lead of the ordinary asynchronous motor, drag the motor with a diesel engine or other power, and the motor has a motor to become a generator, and the synchronous speed of the motor is the rated speed used as a generator; Total capacitance selection: On the motor of more than 1,000 watts, the triangular access capacitor is selected, which can be 10 F (microfarth) per kW and 17 F (microfarth) per kw, and the AC withstand voltage of the capacitor must reach or exceed 400V before it can be used.

This asynchronous generator has an efficiency of up to 80 percent of the original motor power.

Replace the original rotor with one or two pole permanent magnets, and the poles of the permanent magnets should be as close to the stator as possible, but not touch. Turning the rotor (or permanent magnet rotor) can be used by the stator around the output voltage, current. If the speed is increased, the voltage can be raised to a very high level.

The role of the generator and the motor is different, so the design and manufacturing are also different"Success", then its efficiency is also very low.

The motor in the tape recorder is a permanent magnet type and can be used as a generator in turn; The small electric fan hung in the mosquito net in the summer is also a permanent magnet type, and if you pinch the plug with your hand and then flip the blades, you can clearly feel the current generation, and it can also be used as a generator.

Small generators (using small wind turbines as an example) are done as follows:

Tools Raw materials: generators, ABS pipes, metal discs, wood, wires, etc.

1. First of all, buy a generator with a power of 200W and a rated speed of about 400rpm.

2. Then it is to manufacture blades, this master uses this kind of black ABS pipe and slag acorn, which seems to be more common in China, and now the sewer pipes are made of this material. After cutting, it is properly sanded and smooth.

3. Find a metal disc similar to the picture below to connect the generator and the blades, that is, the hub in the generator.

4. Punch holes in the hub, blades and metal discs.

5. Install the blades on the metal disc and hub.

6. Find a hub cover for the hub, which can prevent the screws from being exposed to the wind and sun, and can also play a role in diversion. Beam pins.

7. Make a bracket for putting the generator, just make a wooden one, and then fix the generator with iron wire or iron sheet. Absolutely.

8. Make a connecting rod.

9. Make a tower with water pipes, the bottom of the tower is as follows, and the wires of the generator can be pierced through this hole.

10. Connect the tower and the generator and fix it with a cable-stayed steel cable. A small generator will do the trick.

The practice of small generators is as follows:1. Experimental materials: hand-cranked generator production kit (the core materials include a motor Mingnai, a large light-emitting diode, and several wire gears).

2. Fix the right-angle rod to the bottom of the dust locust vertical retention plate.

3. Install the gears and rockers on the two shafts.

4. Fix the motor to the retention plate.

5. Install the gear rocker to the retaining rod.

6. Connect the light-emitting diode to the top of the motor wire, and shake the rocker to observe the light.

That's how small generators do it.

Step 1: Generator. We have to buy a small generator first, the power is enough at 200w, and then our small wind wheel should not be able to carry it.

Step 2: Manufacture the blades. Jujube Qiaoyi chooses an ABS plastic pipe, (not too thick and not too thin, the diameter is 50-100mm.)

Cut it in the middle and cut it into the shape of a fan page. Grind off the burrs of the fan and smooth the fan blades with fine sandpaper.

Step 3: Make a roulette wheel. Choose a round piece of metal or an axle (note that the sheet is slightly thicker.) Make two holes in parallel on it. Then the edges of the metal sheet are sanded smooth and done.

Step 4: Splicing. It is good to bolt the roulette wheel and the blades we have made, pay attention to the direction of the sash page, and do not install it backwards. That would cause the wheel to reverse, affecting power generation. After the fixation is completed, the roulette is covered with a plastic shell to prevent the roulette from rusting.

Step 5: Assemble. Find a piece of wood or iron, fix the generator on it, and then install a speed-increasing machine between the shaft of the generator and the shaft of the wind wheel, and finally connect the two.

Requires more bai high power.

The small generator set depends on the specific work requirements, and the power that is suitable for the work requirements is the best! Therefore the version of the user is in the selection machine.

When the power of the weight group is not arbitrarily chosen, there are rules to follow!

Determining the power of the generator set is not a simple addition of the power of all the electrical appliances, but also the starting mode of the electrical appliances. The general starting mode is divided into direct start and step-down start or frequency conversion start, the former starting current is about 6 times of the working current, and the instantaneous power will reach 6 times of the rated power; The starting current of the latter is about 3 times, and the instantaneous power is also 3 times the rated power. Therefore, when selecting the power of the generator set, in addition to the sum of the power of all the electrical appliances, it is also necessary to consider the starting power of each electrical appliance.

If the user is not sure about the choice of power of the small generator set, then let the professionals give the accounting!
