Permanent magnets for the rotor of twelve volt generators. According to the request for relevant public information, permanent magnets have strong magnetic field stability and strong magnetic energy density, can produce a stable and strong magnetic field, and improve the efficiency of power generation and the performance of generators compared to traditional electromagnets, permanent magnets. have smaller volume The advantages of small size, light weight and long life can make the generator more compact, light and economical, so the twelve volt generator uses permanent magnet magnets for the rotor.
Yes, there will be a small magnet on the rotor to give the rotor a magnetic field when starting, so that a magnetic field is generated on the rotor, then the mutual inductance will continue like this. Once the voltage is set, the saturation voltage of the champ magnetic will no longer Yes, there are two types of generator heads, one is capacitive type and the other is AVR type. Typically generators have magnets, but some use permanent magnets and others use electromagnets. Since permanent magnets do not consume electrical energy during operation, it is impractical, if not impossible, to change the strength and polarity of the magnetic field, so this is usually the case. used in small generators with low requirements. The large generators you mentioned use electromagnets. This type of magnet is a coil with a certain number of turns wound on the silicon steel sheet on the rotor or stator of the generator. is magnetic, you can change the size and direction of the magnetic field by adjusting the size and direction of the current. Therefore, it is mainly used in large generators with requirementshigher.
