This V-gate motor design will work if you are very careful with the weight of the build. Use common sense and know that it has to weigh practically nothing. Make it from the lightest materials one can find. Such as aluminum and balsa wood. Another important issue is that the rotor wheel is not made or covered with magnets. It is made with ferrite pieces. Ferrite is strongly attracted to magnets. You can't glue opposing neo magnets that close together in a line without them flying all over the place. The mechanical switch magnet (Round) must be small in diameter (to minimize weight) and made from strong neodymium that is of one piece in length. Stacking magnets to make one long actuator magnet won't work. You must have a clean balanced bloch wall that is only found in a one piece magnet length. The spring tension under the support must be experimented with as it actually assists the actuator to help lift the whole mechanical switch assembly at the correct timing of the actuator on the rotor. This is because the spring is compressed from the attraction between the mechanical switch actuator magnet and the ferrites on the wheel as it is turning. The flip magnet under the bottom of the wheel simply falls out when the gate part of the wheel passes it, and comes back up to help pull the wheel as the process continues. Be sure an carefully balance the wheel after gluing the ferrites to the wheel. I would also suggest that you build a flat ramp with the V ferrites attached first. Cover it with plexiglass and test your actuator magnet rolling across the V ferrites. This will allow you to experiment with and find a good strong V pattern that you can then apply to the wheel.
