How to Build an Electric Generator from an Engine (Water Pump) (Part III)

I glued the magnets on the rotor according to Mr. Nelute5 and from the second side, thus: two rows of N/S magnets. However, the result is not satisfactory for me. On the main coil I got a voltage of 46.6V and a frequency of 23Hz, and on the secondary coil I got 46.2V. Connecting the two coils, I finally got a voltage of 66V.
I put half of the rotor with 8 N-polarity magnets and the other half with 8 S-polarity magnets, as I said above for me this result is not satisfactory compared to that obtained from an air conditioner motor. I look forward to your comments if I made a mistake and where I made a mistake. I'll also be back with part four to spin it with a multi-rev motor to max out at 60Hz and see how many volts it can produce.
