Even for the most simple single-phase capacitor motor with double construction group, operating characteristics depend on the manual accounting and its complete is difficult, not to mention the connection of other complex. So, although the tapped control single-phase capacitor motor products
3、 before has been popular in the United states. However, analysis and calculation has been reported about the quantitative. Until the 70's, was initially by the Cyrl G.V einott in the calculation conditions to complete. Since then, along with the computer in the national popularity, from 1975 to
4、1985 about ten years, domestic and foreign single-phase capacitor motor performance of the tap speed-regulating analysis and calculation of the article, like bamboo shoots after a spring rain generally emerge, so that the motor has been widely used in different occasions. Due to the rapid developmen

It is worth mentioning that the centrifugal adopting traditional switch may be PT O components and new electronic starting devices (such as Sinpa
6、c SW itch products like '4' is replaced by. In addition, the development of electronic technology, the advent of the electronic voltage regulator, various types of load regulator, converter and inverter. The characteristics of its low price, excellent performance, reliable operation, the sin
7、gle-phase asynchronous motor is possible from the motor generator simple product to product development From the single-phase asynchronous motor application perspective, some varieties of technology has matured, importance should be attached to its popularization and application. Until this century
8、80 time, almost all types of single-phase asynchronous motor are confined to running as a motor way. In recent years, the development of small hydropower resources, wind resources and biogas energy called reusable (R enew able) energy process, in order to solve the remote area electricity demand, fi
9、nd small single-phase asynchronous generator has the advantages of small volume, simple structure, convenient manufacturing advantages, attention to tradition, there are two asynchronous generator big questions need these two problems of asynchronous generator static excitation capacitor voltage sta
10、bility problem has been the development of fir Yo with capacitor and electronic technology is solved. While running from the theory of single-phase asynchronous generator itself, theI theory and practice of three-phase asynchronous motor based on, as long as the rotor single-phase capacitor inductio
11、n motor speed, making it more than the synchronous speed, naturally reach the generator operation state but, this simple inference is not valid for the single-phase asynchronous generator. According to the characteristics of the generator operating income is very poor, this may also affect a reason
12、for its application. In 1984, the United States E, C. Boardman and other research results presented in the paper, make people break through the traditional prejudice, inspire the motor operation mode of single-phase capacitor type enthusiasm. "'. The results can greatly improve the performa
13、nce of the single-phase asynchronous motor and, paving the way for its application. Can be seen from table 1, single-phase asynchronous motor performance with single phase synchronous generator compared to the United States, and the center height decreased; plus the node peach Li process much more s
14、imple, convenient, this type of generator is very promising. Long-term since, because of single-phase asynchronous motor is only applied in household appliances and medical devices, so the capacity is generally not more than 1 horsepower, often called fractional horsepower motors but, it does not dr
15、aw such a conclusion, namely single-phase asynchronous motor or impossible to the United States of America agricultural electricity as an example the whole horsepower motor excellent output performance students, because the three-phase power supply line is expensive, and the farm and far away from t
16、he center of supply, between farms far apart, each farm needs to load is not heavy, so in order to reduce line Cost, almost all the single-phase power supply so to solve in the single-phase agricultural mobility problems, since the 70's oil crisis, due to rising oil prices, from the book and tur
17、n to the motor too. In the past, due to the lack of a single-phase motor, adopt various single three phase change heat exchanger, since with three-phase asynchronous motor side of rabbit in 80, the design and manufacture of 17 soft start technology problem of large capacity single-phase capacitor ty
18、pe electric drive, so it is more and more widely used. The capacity of up to 100 horsepower. According to China's agricultural situation, many remote Agricultural Pastoral Areas in the construction of John electric line, will also use single-phase John undoubtedly in the economy has taken a few
19、besides, encounter this kind of problem by using small hydro, wind and biogas energy generation, when its capacity is less than 20K W C8) using single phase power more convenient. So, in order to solve the rural irrigation, oil, rice milling and other dynamic problems, the whole horsepower single-ph

21、hronous electric turn U's run in the three-phase power grid, can also run on single-phase power grid can be used as motor operation;, but also as a generator. And draw the wiring diagram and the corresponding list of the matters needing attention in using. This current to our country product var
22、iety is not all, also can yet be regarded as an alternative to do. For a century, more and more varieties of single-phase asynchronous motor. While most of these are achieved by using a variety of winding connection, but little change in motor. However, 8 () generation time, parameters of the motor
23、of Japan's Koichi proposed by Murakami (P.arametric M otor) is a novel motor according to the author's argument, except in the motor starting principle with MI plan consists of divination, the steady operation theory and single-phase asynchronous motor - Peng 81. Because of the motor stator
24、is slotless structure, motor manufacturing diameter smaller more easily. According to the introduction, if the production and electronic tuner to match, in the small device (such as high-speed rotation of the centrifugal separator, separator) get application etc. Therefore, with the development of science and technology, will promote the development of new types of single-phase asynchronous motor, the species will become more and more, will be more and more extensive application.
