Permanent magnet generator providing constant excitation

Technical Field

Background

The permanent magnet generator is a power generation device which converts mechanical energy transformed by heat energy into electric energy. In the conventional dc motor, an excitation method for generating a main pole magnetic field by a dc current is called current excitation. If permanent magnets are used instead of current excitation to produce the main pole field, such machines are referred to as permanent magnet motors. The permanent magnet generator has the advantages of small volume, low loss, high efficiency and the like, and the research on the permanent magnet generator is very necessary today when the energy conservation and the environmental protection are increasingly emphasized. Brushless motors are used in many cases, and therefore, they are used in small-sized and miniature motors. When the variable frequency power supply is adopted for power supply, the permanent magnet motor can also be used for a speed-regulating transmission system. Permanent magnet motors have been widely used in various fields such as household appliances, medical instruments, automobiles, aviation, national defense and the like with the continuous improvement and perfection of the performance of permanent magnet materials.

Excitation is the machine that provides stator power to the generator or synchronous motor stator, provides the working magnetic field for the generator, etc. Sometimes the rotor power supply to the generator rotor is also called excitation. According to different excitation modes of the direct current motor, the excitation modes can be divided into other excitation modes, parallel excitation modes, series excitation modes, complex excitation modes and the like, in the moving process of the direct current motor, the excitation is to control the voltage of a stator to change the magnetic field generated by the stator, the rotating speed of the direct current motor is changed, and the change of the excitation also plays a role in changing the rotating speed.
