The role of magnetizer in the operation of generators and motors

1. Application in generator

    The generator is composed of a magnet system, an armature with a current coil wound on a magnetic material, and a rotating machine that makes the armature rotate. When the generator works, the rotating machinery makes the armature rotate, and the coil on the armature rotates in the magnetic field generated by the magnet system. When cutting the magnetic field lines of the magnetic field, due to the principle of electromagnetic induction, an induced electromotive force is generated in the coil. The current coil is Electric current is generated when it is connected. Then the generator starts to generate electricity. Among them, the role of the magnetizer is to provide permanent magnets for the generator or intermittently magnetize its magnets.

    2. Application in electric motors

    The structure of the motor is similar to that of the generator, and it is also composed of a magnet system, an armature with a current coil wound on a magnetic material, and a rotating mechanism that makes the armature rotate. However, when the motor is working, current is passed through the current coil of the armature from an external power source. According to the principle of the motor, the armature will be rotated by the action of the magnetic field. Therefore, in the motor, the main function of the magnetizer is to provide magnets and magnetizing functions.
