Mostly PM motor - Joe Flynn motor. My attempt to replicate

[Jetijs]

Thanks Steven
Expensive - yes, but nothing compared to industrial dynamometers
How do you expect me to sleep now? I am so excited



Also, judging from the video, he does not use any recovery, because his timing wheel has the gaps exactly the same width as the space between the gaps. If we want to recover any energy, we need at least some time between pulses to get the inductive spike out. This is what Peter calls breathing time

Jetijs that gays a rely com from Italy and they have forum about parallel path motor. I am member of forum and forum is on this adres EnergeticAmbiente.it Forum Fonti Energetiche Rinnovabili forum you may find olmost everything about parallel path.Keko and Mc giver built several replication of parallel path motor including 4 pol and 12 pol.

Thanks!
Will check that out

[Jetijs]

zhorv324,
It is a shame that I do not understand Italian. Do you? I guess yes At least I fished out all the pictures Can you tell me more about the work of the Italian people on that forum? Judging from the pictures, those guys take this very seriously, they have done a beautiful job What is the best efficiency they have managed to get?
Thank you!

Here:
Google Translate

[Jetijs]

Thanks
Those translators do not work very well, but I guess well enough to understand the bottomline Will try this out

LOL, jet, i just had an image in my head of you.....at the next Tesla energy conference or similar.....standing there with an ACTUAL OU motor.....with totally bloodshot eyes from not having slept for like.....27 days lolol.. and a big sh*t eatin grin on your face

[Jetijs]

lol
That would be great!

[zhorv324]

Sory I do not understeend Italian , and yes I use gooogle translator.I ts not good but I understend basic things. I m from Croatia by the way.

Jagged laminations.

If you're careful, you should be able to machine/file those laminations flat where they contact the magnets and then give them a surface coating of epoxy. As long as the finished product allows your rotor the proper clearance, you should be golden.

The laminations need to be cut a little over sized, so the smallest is at least equal to the correct dimension, then the rest filed down to tolerence, so the magnet fits snug. Shims from the same material to fill the gap would alter reluctance.

[Jetijs]

The shaft and rotor assembly is now ready.







The rotor and stator machining will have to wait till Monday. In the mean time I will work on the adjustable timing wheel.
BTW, does someone know how accurate are those virtual bike trainers if I wanted to use one as a dynamometer? I mean if it is off by 10W or so, then it is fine.

Thanks,
Jetijs

Jetis ,may i suggest you about timing.In my case min. on time is 65%, les of that create problem in motor work. By the way happy and successful New Year to all on the forum

[Jetijs]

Hi zhorv324
Of course there will be a minimum ON time, because the rotor has to rotate for some certain distance till the power pulse can be turned off, otherwise the magnets will just pull it back into the alignment. I suppose that this is why there is a minimum ON time. That is good, because if the motor works on less than 100% ON time, there will still be enough time for the inductive spike to leave the coils. This is why I will build an adjustable timing wheel where the timing and the duty cycle will be adjustable, similar to my attraction motors.
Thanks and happy new year to you and everyone else too

[Jetijs]

Hello all.
Made a little progress today.
I made almost all the parts needed for the timing. There are two aluminum discs with gaps. They are bolted together so that the gaps can overlap, this overlap can be changed at will, thus we can get the dutycycle from 0 to 100%. There are also two plexiglass parts. The plexiglass ring fits into a deepening on the bigger plexiglass plate. This allows it to be rotated and this way the timing can be advanced or retarded. The optoswitches are glued in the gaps of the ring 180 degree apart.





Thanks,
Jetijs

LOOKS NICE Jetijs. Looks similiar to a crank shaft sensor set up on a GM 3800 engine. Your work is awesome as usual! Looking forward to more.

Mark

Nice job Jetijs ,bat be aware off mechanic strength your motor easily reach 10000 rpm, and i men sires
