车用硅整流励磁发电机的主要缺点是它的励磁方式，它在发电时，励磁绕组要经

The main disadvantage of the car silicon rectifier excitation generator is its excitation method. When it generates electricity, the excitation winding must be supplied by the battery before it can generate electricity. In this way, when it outputs electric energy, it consumes 20% of its energy first. The excitation type generator itself has an excitation collector ring and carbon brush structure, so it is easy to cause the wear of these two structures when the generator is working, resulting in a short generator life and a high failure rate. Forty percent of the failures of the excitation generator are found in the electromagnet coils in the rotor, and the current price of enameled wires on the market has risen, resulting in an increase in the manufacturing cost of the excitation generator. The structure of the excitation generator is relatively complicated, and there are many parts and procedures to complete the processing, which is difficult to produce. Therefore, the excitation generator is not an ideal vehicle generator. With the continuous development of the automobile industry, while the technical content of electrical components in automobiles continues to increase, the automobile industry has continuously improved the requirements for lightweight, comfort, safety and high efficiency of automobiles. So permanent magnet constant voltage generator is a better choice. The permanent magnet generator has good low-speed power generation performance. Compared with the same power generator, its size is small and the high-speed power generation performance is better. It adopts today's advanced electronic voltage stabilization technology to make its power generation performance reliable and stable. Therefore, after analyzing the different excitation methods of vehicle generators, permanent magnet constant voltage generators are selected for this lawn mower.

The main disadvantage of the car silicon rectifier excitatory generator is its excitation method, it is in the power generation, excitation winding to go through the battery power supply before it can generate electricity, so that when it outputs electricity outward, it first consumes 20% of the energy. The excitatory generator itself has an excitation ring and carbon brush structure, so it is easy for the generator to cause wear on both structures when working, resulting in short generator life and high failure rate. 40% of the failures of excitation generators occur in the coils of electromagnets in the rotor, and now the price of paint cords on the market has risen, resulting in the manufacturing costs of excitation generators have also increased. The structure of excitation generator is also relatively complex, there are many parts and processes to complete, production difficulties. So excitation generators are not ideal auto-generators. With the continuous development of the automobile industry, the automotive industry's requirements for vehicle lightweighting, comfort, safety and high efficiency are constantly increasing while the technical content of electrical components is increasing. Therefore, permanent magnet constant pressure generator is a better choice. Permanent magnet generator low-speed power generation performance is good, compared to the same power generator, its size is small, high-speed power generation performance is also better, the use of today's advanced electronic regulator technology, so that its power generation performance is reliable and stable. Therefore, after the car generator different excitation method analysis, in this lawn mower choose to use permanent magnet constant pressure generator.

The main disadvantage of the vehicle silicon rectifier excitation generator is its excitation mode. When it generates electricity, the excitation winding can generate electricity only after being powered by the battery. In this way, when it outputs electric energy, it consumes 20% of its own energy first. The excitation generator itself has the excitation collector ring and carbon brush structure, so it is easy to cause the wear of these two structures when the generator is working, resulting in short life and high failure rate of the generator. 40% of the faults of the excitation generator are on the electromagnet coil in the rotor, and now the price of enameled wire on the market is rising, which causes the manufacturing cost of the excitation generator to rise. The structure of excitation generator is relatively complex, there are many parts and processes to complete, production is difficult. So the excitation generator is not an ideal vehicle generator. With the continuous development of the automobile industry, the technical content of electrical components in the automobile is increasing. At the same time, the requirements of the automobile industry for lightweight, comfort, safety and efficiency are increasing. So permanent magnet constant voltage generator is a better choice. Compared with the same power generator, the low-speed power generation performance of permanent magnet generator is better. Compared with the same power generator, its small size and high-speed power generation performance are also better. Today's advanced electronic voltage stabilizing technology makes its power generation performance reliable and stable. Therefore, through the analysis of different excitation modes of vehicle generator, permanent magnet constant voltage generator is selected for this mower.<br>
