摘  要：本文是對小型變頻單相電容運轉電機做的一個基本的研究。這種電機主要用做中央空調送風系統的動力部件。本文主要闡述了單相電容運轉電機的原理，變頻技術的原理。對單相電容運轉電機做了結構設計和電磁設計，選擇了適當的變頻器來調速。
 本文提出的變頻調速控制方法具有系統設計簡單易實現，調速范圍大，動態響應快等特點。在系統設計過程中，本文采用美國TI公司生產的TMS320C24X系列DS作為系統控制器。不僅滿足了單相電動機變頻調速控制的實時性要求，而目使系統的硬件電路變得更加簡單。
 最后，將變頻后的性能參數和抽頭調速時電機的性能參數進行了比較，對比結果驗證了單相電動機電壓矢量式PWM變頻調速控制方法的可行性。變頻調速是一更為先進的調速方法。

The central air condition of frequency that change the design sends the breeze electric motor YSK98-6

 Abstract:This text is to small scaled change the frequency single mutually the electric capacity revolves a basic research that electrical engineering do.This kind of electrical engineering uses primarily the central air condition that do the motive parts sends the breeze system.This text expatiated primarily single mutually the electric capacity revolves the principle of the electrical engineering, change the principle of the technique of frequency .To single mutually the electric capacity revolves the electrical engineering did the construction designs to design with the electromagnetism, choosing to change the machine of frequency to adjust appropriately soon.
 This text puts forward of change the frequency adjusts to control the method a systematic design soon to realizes in brief and easily, adjusting soon the scope is big, the development responds to quick etc. characteristics.In system design process, TMS320C24X series DS conduct and actions system controller that this literary grace produce with the TI company of the United States.Not only satisfied single mutually the electric motor changes the frequency adjusts soon the solid hour that control requests, but eyes make the hardware electric circuit of the system become more in brief.
 Finally, would change the function parameter of the frequency empress to proceed the comparison with a function for adjusting soon hour electrical engineering parameter, contrast the result verified single mutually the electric motor electric voltage direction measures the type PWM changes the frequency adjusts soon possibility of controling the method.Changing the frequency adjust to is on adjusting more advancedly soon soon method.
 Key phrase:Changing the frequency adjusts soon    single mutually the electrical engineering    circulates the function
