[Prior Art] Most of the products in the daily life require electric drive, so power is an important energy that cannot be lacked in today's life. Energy can be produced from a variety of different sources and can be converted, or directly, to provide heat, light, and power. The most common source of energy is obtained through fossil fuels such as natural oil, natural gas, and coal. Energy is generated by burning fossil fuels for the engine to drive the car or to use the steam to propel the turbine to produce electricity. However, in the process of burning fossil fuels, air pollution problems are inevitably generated, and burning fossil fuels is a high-loss rate of energy generation, and the total amount of fossil fuel in the crust is rapidly decreasing, so by burning Petrochemical fuels are called for energy and are not always viable. Other natural power generation methods such as solar energy, wind power and tidal power generation can generate electricity', but the power it can generate is limited, and most of the conversion devices required are bulky. Although environmentally friendly, it is difficult to fully use it in daily life. Many areas for improvement. For example, the battery 'is generally used for portable products. Considering the small size of the portable products, it is convenient to use the battery as a power source, but no matter what kind of battery is using the chemical reaction as the generator system, there are also 201128908.

The magnetic devices are used to generate induced currents through the induction coils, and the external devices connected thereto are supplied with power, which is converted into heat, light energy or power. At present, the common power generation devices are mostly rotary rotors that move the movers. Although the principle is based on electromagnetic effects, the energy conversion process is often caused by friction, which is a shortcoming that needs to be improved.
