How to make a manual generator:

Preparing materials: small toy engine, wooden board, round pencil tip, latex, rubber band, small light bulb , triangular steel.

Operation steps:

1. First fix the small toy motor on the wooden board, take a 6mm round pencil tip, remove the lead core, and use a triangular steel to form. a belt Oops, make a small pulley, as shown in the picture below.

2. Use latex to glue the small pulley to the small motor. Make a large pulley from two layers of wood as shown in the picture below.

3. Fix the large pulley on the wooden board and install the crank. Put the rubber band on the small pulley and the big pulley, as shown in the picture below.

4. Connect the small bulb to the two wiring points of the small motor and quickly shake the large handlee pulley so that the small motor generates electricity to light the small bulb. completed, as shown in the figure below. Display.

Let me answer:

1. Rare earth permanent magnets are a matter of materials and have nothing to do with the principle of power generation Relationship, as long as it is a magnet, it can produce electricity. A stronger magnetic field can reduce the size of the generator, saving materials and labor losses. Many factors affect electricity production. It mainly depends on how many kilowatts of generator you want to make. But for various factors, they are ultimately reflected in the change in magnetic flux in the closed loop.

2. Is the position of the NS pole not shown in the picture? Magnetic field lines on a horizontal plane must be vertical. But as soon as it leaves the magnet, the level changes.

3. The thickness direction should be the direction you marked. The presence of electricity when a copper wire rotates around the outer diameter of the magnet depends on whether there is a change in the magnetic flux in the loop formed by the copper wire. If the magnetic flux changes, there will be electricity. There is no change, there will be no electricity. The basis for cutting magnetic lines of force is changing the magnetic flux of the loop.

4. Permanent magnets have significant residual magnetism after being magnetized and can be kept for a long time with little change, which is why they are called permanent magnets, but they will also decrease. Once the soft iron is magnetized, there will be very little residual magnetism after the magnetizer leaves. The KG value and the T value are just a few parameters for mesecure the magnets.

5. Maximum magnetic energy product: (KJ/m3: standard value 342, minimum value 326) (MGOe: standard value 42, minimum value 40), is this a factor affecting power generation capacity? It should also be parameters that characterize certain aspects of the magnet. Power generation capacity will definitely increase with strong magnets, but power generation capacity always depends on the size of the generator you design.

Note: The concepts of electricity generation, electricity generation capacity and electricity generation are different.

First disassemble the motor from the toy, being careful not to break the two wires. Toy motors are mostly small DC motors, usually with two wires, one red and one black. Also note that the parts of its transmission mechanism cannot be losts. Some small cars have rear wheels and motors driven together, which is simpler to make.

Make the transmission mechanism mounting bracket as required. Measure the size and drill holes. Make the rocker arm at the end of the transmission mechanism.

Remove the flashlight head and the light should still be on. Pay attention to the red and black lines, red positive and black negative.

Fix the engine and transmission mechanism to the prepared support. And connect the red and black wires of the bulb to the red and black wires of the motor. Be careful not to log in incorrectly.

It's basically a success. I can't help but turn the transmission mechanism and try it. If the light does not come on, it means you are turning in the wrong direction.

Make sure the light is on and the box is ready.

Fix itbulb head to the front of the box and install the mechanism into the box.

Fix the rocker plate with screws, turn the rocker handle and the light will turn on. Be careful not to turn too quickly. If the voltage is too high, the lamp will fail. Because most flashlights are bright light-emitting diodes.
