1、变频器最牛逼的公司

For my own, the following ranking is totally personial.

ABB Group | Helping industries outrun – leaner and cleaner — ABB Group

汇川技术 - 推进工业文明 共创美好生活

2、变频器有什么用

To control the motor running as you wish, that is VFD's function.

If you have a Xiaomi SU7 Ultra, you have a Variable Frequence Drive, Variable Frequency Drive, VFD for short.

3、基本原理

It doesn't matter what power supply you use, as long as VFD can give the motor the right current and voltage. That is the basic principle. 

Turn AC to DC, then transform the DC to the right AC. Feed motor with AC as it wish.

For now, I donot know how to write the test runs. This is all I know. But the VFD is much more than this. Today have to think what to learn next and go on tomorrow.

Do first and adjust next.
