## Summary:

- Building a three phase motor need help figuring out how many poles.

## Main Question or Discussion Point

Hello. I am building a three phase motor for a science project of mine. I am trying to match my motor with an inverter so i need to count how many poles I have in this motor. The problem is that I have read about this and some people say that this.

There is a thread it shows two diagrams one is the top one that shows a 2 pole three phase motor. There is another below it that shows a 4 pole three phase motor. This explanation should be straight forward but i also see motors with this coil arrangement.

How do you calculate the poles of a three phase motor with 3 coils per phase? Thanks for any help.
