The video demonstrates a floating solar engine, a toy purchased from China, which uses solar panels, magnets, and a unique motor design to rotate without any external power source. The motor, called a "switching motor by Light," works by using the sun's light to activate coils and create an electromagnet, causing the motor to rotate.
The video explains the theory behind the motor's design, including the use of neodymium magnets and solar panels to generate energy. The host also demonstrates the motor's ability to float and rotate, measuring its speed at around 900rpm.
The video also explores the motor's limitations, including its inability to function with artificial light sources. The host attempts to use a flashlight to power the motor but is only successful with a stronger light source.
Finally, the video disassembles the motor to reveal its internal components, including two coils and a unique wiring system. The host also experiments with connecting the motor to a DVD motor and a power source, demonstrating the potential for creative uses of the solar engine.
Here are the key facts extracted from the text:
1. The device being tested is a floating solar engine.
2. The solar engine was purchased from China and is very successful there.
3. The engine has four solar panels, a small fan, magnets, and a base.
4. The engine floats on top of the base and rotates using only light.
5. The engine has four magnets on the bottom and 16 magnets on the base in the shape of a ring.
6. The magnets interact with each other, causing the engine to rotate.
7. The engine has two coils of wire inside.
8. When the sun shines on the solar panels, it sends energy to the coils.
9. The coils turn into electromagnets when electrical energy is applied to them.
10. The electromagnets interact with the magnets, causing the engine to rotate.
11. The engine is called a commutation motor by Light.
12. The engine uses a simple method of commutation using magnets and light.
13. The engine can rotate at 900 revolutions per minute (rpm).
14. The engine can be powered by artificial light, but it requires a certain intensity of light to function.
15. A 300-watt lamp can be used to power the engine, but it may not perform better due to the spread of light.
16. The engine has two coils connected to two plates at the same time.
17. The engine can generate 0.51 volts when exposed to sunlight.
18. The engine can be connected to a DVD motor to test its functionality.
