I bought some weeks ago an electrical generator that uses water pressure to produce electricity.
I have disassembled the generator and I don't fully understand how it works.
It is like this one:
The motor
I supose that there is a magnet somewhere that alternates between north and south when the piece in the right (the picture that has 2 pieces) rotates. There is only one magnet? maybe more?
That appears to be built on outrunner style where the rotor is on the outside with the stator coils on the inside.
There should be a number of magnets on the rotor normally.
See the Fisher-Paykel motor for the motor version or any RC outrunner. **broken link removed**
Max.

Are you refering to this? (left one) **broken link removed**
I have checked the link you have wrote and I understand a little bit better the concept. The magnet(s) must be on the rotor. But... there are small magnets like in the above picture or just only one magnet?
(this is a ferrite core, but I post the picture here to get an idea about how the magnet would look like)
The rotor almost certainly contains a ring magnet with multiple poles. You can check the number of poles by running a paper-clip, nail, etc around the inside of the ring and counting the "notches" you feel.
