To build 110-220V Keppe Motors is much more interesting than with low voltages, and as long as you take the proper care, results shall be even better.
The idea behind the Keppe Motor is that current is "loss of energy" and voltage is "energy itself". Therefore, the more you increase the voltage and diminish the current, the better (Be careful with high voltages!!!)
We suggest you to build a rotor with 6 cylinder stacked neodimium magnets (22mmx10mm) and use two coils at right angles with each other. The coils can have wire gauge AWG-28 or 29 and 1200 turns in each sector of the stator, i.e., 1200 turns below the shaft and 1200 above it. All together, each coil should have 2400 turns.
You will need two reed switches, one for each coil, also 90 degrees out of phase. With this configuration you have a 2-pulse Keppe Motor appropriate for 110V and it will be strong enough to run a fan blade very fast with low consumption.
Remember to put one 50 or 70Amp car relay connected to each reed switch, so that it can stand the voltage peaks of 110V power supply. Also, don't forget to rectify the alternating voltage with diodes or a rectifying bridge.
Do this and see the result for yourself. In case you need more details, ask for the KM Manual 3.0 or ask help for a friend who is skilled in electronics and build it together with him. You'll learn a lot and get amazed with the result.
Good luck!
