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.

liestener,luc

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?

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.
