    I watched each one of those again - what's wrong with me, I have work to do! :-)
    what a teaser - non standard trigger - Cap/resistor combo?
    Radiator fan, you must be working on a drone...
    Take care,

    Hello Patrick.
    We haven't talked since I provoked the wrath of the UFO Platoon. I've been working on several small circuits that might be a slightly different approach to achieving Under Unity. LOL. I haven't been posting the video because I think my viewers are getting tired of the same old stuff. Never the less there might be something that someone could elaborate on and turn it into something useful. One thing that was very surprising was the circuit can run an unmodified three phase motor and do a fair job of charging. I think the effect is a little more like a Buck Boost converter and the charge might be more appropriate for a cap dump circuit, but anyway I want to make sure I have some diagrams and a few decent experiments before I post the video.
    Take care Patrick
    John
    PS. I don't think there's anything wrong with you Patrick. You've been one of the hardest workers I've run into in this quest.

    There's been many different kinds of window motors built through the years. There have been some pretty good threads about them as well. I'm sorry to say I don't remember where they where to help you out with that. You will have some digging to do. I'll share a few of my experiences with you if it will help. There are pictures of a jig for winding coils. A rectangle coil is not the only coil to wind for a motor. If you are using three coils it is beneficial to use a wooden jig like is pictured in some of JB's literature. Again, I don't have instant reference to it but is is there. The issue of using an iron core or rotor is a mater of preference. I have used both iron and Delrin. I personally prefer a mild steel rotor. I do not use a hex shape and prefer to mill slots for the magnets. I'm not sure what you mean by a compound configuration but you should use six magnets with alternating poles outward on the faces. This is the best way to start but experimenting with what is known as a notch rotor also has some interesting results. Your windings can vary dramatically depending on what you are trying to accomplish. Higher turns ratios say in the 400 turns or more will give you a slower but stronger motor that is easy to trigger and has low current draw. Less turns say in the 200-300 turns area will give higher RPM's with less torque but higher current draw. The WM can run from an SSG, half wave, full wave or Single Coil Motor Circuit. In all cases you are not likely to have charging results that would be better than a monopole motor. I would suggest winding two triggers and one power coil or better yet add an additional power coil to experiment with a generator circuit. If you haven't been there yet, you are welcome to visit my channel where I have some videos of a small and very efficient motors. The first one shows how I constructed mine. Here are a few links:
    Window Motor Assembly And Capacitor Test - YouTube
    Window Motor Running On Capacitors - YouTube
    Window Motor On Water Battery & Solar + (Notch Rotor) - YouTube
    There is other videos that pertain to the window motors there as well. I hope something here might be of some use to you since you are just starting to learn about these fun motors. I will be posting some other videos soon with a different style motors running from a circuit that doesn't require a standard trigger source so you may want to check back later as well.
    Take care.

    The Window motor has a set of Permenant Magnets as its Rotor, so why would you need a Iron there?
    you need a rectriangle frame on which to wind your coils, the coils can be hand wound (no need for a jig) just that make arrangements to support this frame firmly to withstand the high-speed and torque produced.

    I am in the process of building a window motor. I have some questions.
    Is there a picture of a jig for winding the coils so the shaft will go through?
    Can I use an Iron core for the rotor?
    Can I use a compound neo magnet configuration on the iron rotor?
    Thanks for your help Jeff Joseph
