The design of the electric capacity starting and the operating electrical motor for the revolved YD—750 compressor which speed could be adjusted by changing the band

Abstract：Aim at more and more demand of the high-quality air condition machine in the market and such problems with the air condition machine as the rate between energe and efficiency, the noise, the confort of human body etc. I put forward realizing and improving the above resort problems and the fucation of the air condition machine with the compressor which speed could be adjusted by changing the band. Passing by analyse the principal of starting and revolving single mutually electrical capacity electrical motor, the design of the electromagnetism and the research of the reasons when it is adjusting the speed by the band-changing machine. I designed a kind of a worth electrical capacity electrical motor that satisfy the general requests.
Keywords：Single mutually electrical motor; Adjusted by changing the band; The operating of the electrical capacity; The operating of the electrical capacity; A worth electrical capacity
