It doesn't come through as rude, and I am grateful that you are doing what you do. Alas having moved house three times in the last two years I gave away all my magnets and bits and pieces to Grumage. I am not convinced the idea will work but an FEMM simulation does show a small average torque in one direction, but that is much smaller than the peak torques that occur in both directions. The pantograph method for keeping things parallel as seen on the link rod on steam locomotives could be one answer, see image below.

An analysis of the Ferris Wheel magnet motor: In the first model with the rotor rotating at speed when the pivot is going CW up through the 9:00 position the weight nearly doubles. Then as it goes from left to right across the 12:00 position the weight lags behind but as the pivot goes down through 3:00 the weight is weightless and still traveling from left to right. At this point, 6:00, it is possible for the weight to do a full loop around the pivot. However this is not the reason it doesn't work, mearly an indication that this design is limited to very low speeds. As the north pole of the rotor magnet moves towards the south pole of the stator magnet there is attraction... an energy gain. However when the two magnets are edge to edge they so attract to each other so as to lock. To continue the same rotation direction, energy must be provided to break the lock. Thus all the energy gained on attract in must be spent to overcome the lock. But wait, there is more, as you slide the north pole down the length of the stator maget we have a situation where we have two like poles are approaching, a repulse situation so twice as much energy is required to continue rotation. This doesn't happen. as the rotation ceases at the lock position. The two rotor concept, while clever, will suffer from the same restriction. Both versions have the same problem with alignment. When the rotor magnet is positioned in repell (if you could get it there) it is fully half a diameter above the stator magnet and the repell is nonexistant. You can see this in the video where at one point as I demonstate the weak repulsion I let the rotor go CCW and the the rotor magnet is attracted in and fired out in reverse. However it is then attacted back in to lock as at the end of the video. Oh, do you like my tomato grow op in the background? I have 7 out in the green house, as they were getting too big.... frost this AM, ugh Take care Ron
