Hi Gotoluc,

Perhaps this makes it clearer.

If you check Pierre's explanation video screenshot in https://i.imgur.com/NkNCryA.png - the solution would be full bridge on each coil including BEMF recovery circuit.

30 coils would mean 30 full bridge circuits.

attention les sorties out1 et out2 sont en court-circuit sur le schéma  Reply #120.

beware the out1 and out2 outputs are shorted on the Reply # 120 schema.

Yes, that makes it clear now but changes everything!... I'm not sure if that's how TK envisioned his program to work and maybe if we had 30 it could handle more overall current?
Why did you not say something earlier when I made the video on page 3 or then when TK posted his 30 coil program?
Regards
Luc

Fr. Oui, cela le rend clair maintenant mais change touts!  Je ne sais pas si c'est comme ça que TK a imaginé que son programme fonctionne et peut-être que si nous en avions 30, il pourrait gérer plus de courant global?
Pourquoi n'avez-vous pas dit quelque chose plus tôt quand j'ai fait la vidéo à la page 3 et quand TK a publié son programme de 30 bobine?
Cordialement

Hi T-1000,

Originally that's what I planned for in the case of the 36 slot stator i.e  36 H bridges.
This was on the assumption that each coil was switched separately by it own H bridge however, what Pierre is showing in that diagram, is 36 half bridges each one created by two single pole relays and all 36 coils in series which is quiet a different arrangement.

So each high side relay that's on, is paired with low side relay thats on, 6 coils further around the series.

To achieve that scheme electronically you have to use a half bridge configuration.

Also what emerged was the current required by the six coil series, intimated to be 10A, at least that's the rating of the relays. So really now the L298N's for me at least are only a connection proving tool and I plan to use a  much more robust half bridge with 45A 45V rating and built in opto isolation, over current protection etc.

Hi Gotoluc,

Quite simply I am spending time building the stator, so I have not spent time on the software, or anything else.
If I stop and do all you are requesting, i.e. make a schematic that shows the exact connection scheme, write the code etc, then I wont get my own build done.

Regards

Why are there less than 36 connections coming from the stator? => 28!? maybe 24?

should be 72 !

Dear L192

I'm not saying you should do all those things but your idea sounds good and I just wish you would of wrote a message.
I appreciate your help and participation but your suggestion (which sounds good) changes everything. Just wish I knew about it earlier so we could all consider the pros and cons as a group.
Kind regards
Luc

Fr. Cher L192

Je ne dis pas que vous devriez faire toutes ces choses mais votre idée semble bonne et j'aimerais juste que vous écriviez un message.
J'apprécie votre aide et votre participation, mais votre suggestion (qui sonne bien) change tout. Je souhaite juste que je le savais plus tôt afin que nous puissions tous considérer les avantages et les inconvénients en tant que groupe.
Sincères amitiés
Luc

Hi r2fpl,

He probably has the coil connected in series at the stator and then just pulls 36 wires down to the relays.

Hi Gotoluc,

I normally write my own software, so the only reason I looked at the TK software is that you said that is what you plan to use with the L298N boards.
Sorry but I don't analyze everything that is posted.

Forgive me for asking and please don't take this the wrong way but how do you manage to function in this environment without having all the necessary skills?

Please remember I know nothing about the individuals on this forum.. is this how it is for many members?

Regards

L192

Hi listener191,

No, See ... only 4 plugs, Full cables in 3 plugs. 4 plugs is 4 cables. Total=28 !

not 36 or not 72.

How connect this ? It is impossible. How it is to the program Arduino ?

Hi ARTIMOSAT,

Yes this is intentional, both sides of the H bridge are driven together to produce a half bridge with nearly double the current capacity.

@L192
Looking at your total post count I now see you probably haven't been member for very long and understandably don't know who's who.
The research work I usually do is not replications. It's usually my own ideas based on electro and permanent magnets experiments which I share.
From my well known history and readiness to truly build and share video test results, if I need any electronics help usually well versed electronic engineer like TK and other members of this forum will help.
Sorry if I made you feel bad, it's not my intention. Just disappointed something so simple was not thought of or understood earlier.
Thanks for making it clear.
Slider2732 is now looking over your suggestion to see if it's the direction we will take. Anyone else is also free to do so and share your pros and cons.
Regards
Luc

Fr. @ L192
En regardant votre nombre total de messages, je vois maintenant que vous n'avez probablement pas été membre depuis très longtemps et, naturellement, tu ne sais pas qui est qui.
Le travail de recherche que je fais habituellement n'est pas une répétition. C'est habituellement mes propres idées basées sur des expériences d'électro et d'aimants permanents que je partage.
De mon histoire bien connue et prêt à vraiment construire et partager les résultats des tests vidéo, si j'ai besoin d'aide électronique généralement un ingénieur électronique bien versé comme TK et d'autres membres de ce forum aidera.
Désolé si je vous ai fait mal, ce n'est pas mon intention. Juste déçu quelque chose de si simple n'a pas été pensé ou compris plus tôt.
Merci de le préciser.
Slider2732 regarde maintenant votre suggestion pour voir si c'est le chemin que nous prendrons. Tout le monde est également libre de le faire et de partager vos avantages et inconvénients.
Cordialement
Luc
