Good job! I like the recovery of the flybackvery great work with that!! I have lots of those SSRs and have built a few H switchers with them too, the SSRs are fairly slow, you would get better flyback recovery results pulling the flyback out using single mosfets and protect and isolate the gates etc but the SSRs sure are easy to work with. "Would be fun" to have two fully isolated circuits, each one with own battery, own cap, and like two DC pulse circuits, and then send the backemf/recoil/flyback from circuit A's capacitor right over to circuit B's capacitor every time, and vice versa. I have video here, very interesting it has an H switcher with SSRs like you have, then the voltage from battery is boosted up with a DC to DC boost convertor to 48VDC or something before it hits the H switcher. What is interesting is when shaft gets loaded, the voltage going into the little "AC" motor I built ....the voltage goes up from 48VDC to 71VDC (!) And the draw drops down going into battery from 1.95 to 1.5 as well. So a motor that draws less when shaft loaded, thats something good eh. Look how I space the 4 NSNS magnets it rotor, with also 4 coils each side of rotor. Look at other video too down below with the big 2" magnets which explains it better. Idea is coils with ferrite cores "strech" across two magnets in rotor at once, so you get double power, one coil pulls the other pushes and there are four coils all getting the same "push pull" simultaneous treatment. This could be why draw goes down, or maybe something to do with the DC to DC boost convertor not sure why it does this but it does. I still have this motor, it is one of my most favorite AC motor designs. I also did this on a big scale with 2" wide neodymiums, (video of it below this video) and it worked well, but didnt see the draw go down with that one - the spacing wider in it. ua-cam.com/video/fGADDM7F5jc/v-deo.html Here is the big version as mentioned of this AC motor design and explains how it works: ua-cam.com/video/wuq92YQKmbk/v-deo.html Also I ran a rotovertor off this SSR H switcher, used the spinning timing disc with a couple magnets at 180 degrees whipping past hall effects at 90 degrees to get AC happening, and can control the rpms like this too this pretty decent video, showing a fred flintstone VFD in action: ua-cam.com/video/gaRIi_pLJpw/v-deo.html
@@energyhack3538, But actually, there is more here that I didn't say, man. You made a regenerative VFD drive. Do you know what that is? These regen VFD units are very expensive due to how efficient they are. When the VFD shuts down, it captures the back EMF into a capacitor (bus bar) bank. Sometimes, they use a "Regenerative Dynamic Braking Resistor for Servo drives". Now, these regen VFDs are very programmable. You can program the on/off cycle, whatever you want, to dump the back EMF into the battery bank instead of the capacitor bus bar or Dynamic Braking Resistor. I wonder by using a regen VFD, if you can charge the source battery? This guy explains how these devices works ua-cam.com/video/IAnMVYOYHxg/v-deo.html
I think the RV uses a 3-phase motor but wires it single phase and then drives a generator. Capacitors are necessary to tune it. They claim it’s mildly OU but I don’t understand how.
@energyhack3538 The RV (rotoverter) may work as a synchronous condenser generating OU electricity by parametric excitation. By placing a transformer in series with the rotoverter it is allegedly possible to loop it. I haven't seen it done or done it myself. You may have a switch here that could run a RV self looped. I thought I would suggest it since you have everything on the bench except a 3 phase motor with degreased bearings, and a series capacitor. You could ask MrDKONZEN on YT for help. He will definitely give you the time of day. Maybe you guys are close by in USA. Best wishes.

That's really really cool Great work man that opens up new possibilities 👍💯⚡
Looks like you just made a VFD drive. It's good to know that we can do these things. God job.
I realized that half way through the project. 😂

Admire your passion. I wonder if battery likes hundreds volts emf
Very nice ! Runs smoothly
What happened with you RPG motor videos?
Thx K. I took them down being frustrated with the project for not getting better results.
@ I’ve been working on that type lately with very small optical timing ill tx you the scope shot
Kinda nice, but now you need to add an extra phase, pwm and Park Clark transforms. Them you'll be catching up with everyone else. Just saying 😂😂
Thanks for sharing. Are you familliar with the rotoverter? It might be interesting to see if you can run one with this.

@energyhack3538 YT deleted my response. Hopefully you got it via email.
can you try if possible induction motors run on half wave AC?
@@sticker89 yes, I did try that and it will on half wave as well but it needs full wave to start and once up to speed you can run on half wave only.
