permanent magnet motor test bench is essentially an energy conversion device (exchange of electric power and mechanical energy) composed of a motor and a generator. In industry, the motor is more common, so the narrow sense of the motor generally refers to the motor.

A simple motor consists of batteries, screws, wires, magnets, and fans. Can you be smart enough to understand why the fan blades can turn?

The motor uses a material called an electromagnet, the so-called "magnet", which is a natural magnetic material that can suck metal fragments away like magic and then keep moving in the same direction. The Chinese first discovered and used the magnet and used it to create the "compass", one of China's four great inventions ".

So, what is the connection between magnets and permanent magnet motors? A permanent magnet motor is a motor made of magnets, but its name is not so high-end, it is called "permanent magnet". The theory of electricity and magnetism has been known for a long time, but before the 19th century, the study of electricity and magnetism was only in its infancy, and most physicists believed that electricity and magnetism were two completely different concepts. At the end of an industrial revolution, electromagnetic technology developed rapidly, that is, the second industrial revolution, Oster, Ampere, Faraday, Gauss, the main work of these people were completed between 1820 and 1831, while Maxwell, under the leadership of Maxwell, established a complete set of electromagnetic theory. During this period, the basic theory and engineering realization of the motor have been basically formed, so the research on the motor and the understanding of the development process of electromagnetic theory is particularly important.
