    Tips: How does a permanent magnet generator generate electricity?

    A permanent magnet generator is a power generation device that converts mechanical energy converted from thermal energy into electrical energy. The rotor of the permanent magnet generator is made of ferromagnetic ferrite and has no rotor coil. When the rotor is rotated by an external force, it is equivalent to the stator coil cutting magnetic lines of force, generating induced voltage to generate electricity.
    The permanent magnet generator can maintain its magnetic field without external energy, but it also makes it difficult to adjust and control the magnetic field from the outside. These limits the range of applications of permanent magnet generators. However, with the rapid development of control technologies for power electronic devices such as MOSFETs and IGBTTs, permanent magnet generators do not require magnetic field control in application and only perform motor output control. The design requires the combination of NdFeB materials, power electronics and microcomputer control to make the permanent magnet generators operate under new conditions.

    I will buy again
    Better than I thought, the alternator generator received is much better than the picture, the structure is compact, and the quality looks good. I will use it DIY a turbine generator, I am looking forward to using it.
