摘要：本文是对小型变频单相电容运转电机做的一个基本的研究。这种电机主要用做中央空调送风系统的动力部件。本文主要阐述了单相电容运转电机的原理，变频技术的原理。对单相电容运转电机做了结构设计和电磁设计，选择了适当的变频器来调速。
本文提出的变频调速控制方法具有系统设计简单易实现，调速范围大，动态响应快等特点。在系统设计过程中，本文采用美国TI公司生产的TMS320C24X系列DS作为系统控制器。不仅满足了单相电动机变频调速控制的实时性要求，而目使系统的硬件电路变得更加简单。
最后，将变频后的性能参数和抽头调速时电机的性能参数进行了比较，对比结果验证了单相电动机电压矢量式PWM变频调速控制方法的可行性。变频调速是一更为先进的调速方法。

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
