Hello Kashif,

 

you will find that if you ask a "specific" question, that you are more likely to receive a reply from the Forum members.

 

To advise you on "how" to design and make anything.... such as a "low cost digital power factor meter" or a PMSM type motor..... is beyond the scope of this Forum and you will find that you do not receive any replies.

 

It is also necessary that you have a Fundamental Knowledge of what power factor is, of how to measure it using analog instrumentation such as the analog voltage meter, the analog current meter, the analog wattmeter, analog power factor meter, etc. and from that knowledge, you will be prepared to learn how the digital versions of those meters are designed.

 

With that knowledge, you will then be better prepared to attempt the design of a low cost digital power factor meter.

 

You may also use a search engine, such as Google, to find information helpful to you.

 

Good luck with your project.

thankyou for your kind information

dear i know basic knowledge about power factor measurement using analog and i also know to use CT ant PT and then using a2D conversion to achiece bits, but further what i can perform to get power factor , woild i perform the or operation o get power factor???
