Static magnet generator principle

          Static magnet generator principle: by adding an alternating voltage to the magnetizing coil, changing the direction of the magnetic line of the closed magnetic circuit; and sensing by the change of the direction of the magnetic line of the closed magnetic circuit The magnetic field line of the open magnetic circuit is changed to generate an electromotive force by electromagnetic induction in the induction coil.

          The size of the electric depends on the size of the generator. Even if the motor goes to 1000 rpm, there is only a small amount of electricity. Large generators are non-magnet. Generally, a low-power magnet is used. High-power generators use excitation to generate electricity, that is, the rotor and stator wires are connected together. To generate electricity, first send a little electricity to the stator, and rotate the generator at the same time, so that the rotor coil will cut the weak magnetic field generated by the stator, and the generated electricity flows into the stator again, so that the cycle generates electricity.

          But the generator needs some instruments to stabilize and control the flow of electricity. So there is a control box on the generator. If there is no control box to control the power supplied by the rotor to the stator coil, the magnet will cause higher voltage and current, which will cause the stator or rotor to burn out due to the high current and voltage.
