The permanent magnet generator is a new type of generator based on permanent magnets. Its working principle can be divided into the following steps.

In the first step, the permanent magnet generates a magnetic field. Permanent magnets are made of highly magnetic materials, such as NdFeB and ferrite. When permanent magnets are at rest, they produce a constant magnetic field.

In the second step, the rotor rotates into the magnetic field region. The rotor is the part of the power source that is connected to the generator, such as the wind wheel in a wind turbine. When the rotor rotates in the magnetic field, the magnetic flux of the magnetic field is changing. This changing magnetic field stimulates the flow of electrons in the wire, creating an electric current in the wire.

In the third step, current flows into the circuit. When electricity flows from a wire, it is transferred to a transformer or electronic device, such as a battery or generator circuit board. The flow of electrical current can be used to power electronic devices.

The fourth step is to generate the specified current in the power supply. Such power supplies include excitation power supplies and direct drive power supplies. In an excitation power supply, the current is supplied from an external source. In a direct drive power supply, the generator’s rotor coils drive the rotor directly to produce electricity.

The permanent magnet generator takes advantage of the magnetic field of permanent magnets and does not require the support of an external magnetic field. At the same time, the power provided by this generator is more stable and reliable. It is suitable for use in wind power generation, solar power stations, hydropower stations, etc. Compared with traditional generators, permanent magnet generators have the advantages of high efficiency and low maintenance costs, and are the development trend in future industrial production.
