I could have got thinner laminates laser cut but not for an experiment at $300. Ended up attaching the individual laminates to an angle grinder and spinning them against the bench grinder. Serpentine initially it will be a 3 phase rotor 4 strands of 0.4mm in each coil 13m in length. The photo is the 1st phase.

Thanks for reply.
Doesn't that put a 4-pole rotor in a 2-pole stator, or am I missing something?

Thinking further, that serpentine wind results in 4 pole pairs, or 8 poles. Be interesting to see how it behaves.

Hello Jimboot,
Any progress? Do any test?

Thanks for asking Bi. At this stage I have a bad transformer. I'm using the Zafer BLDC 3 phase driver as shared in Ciftas thread. My 3 serpentine coils are 25 turns and I do get a sine wave off a stator phase. The rotor coils are just underr 1 ohm and at least one is damaged. I was hoping to just turn them into bifilar serpentines but it looks like I have conductivity between strands. Any way 4.5 v around 1 amp in measures around 20v on the stator but there is barely enough current to dimly light an led. I'd like to try some coils at around 3-5ohms next. I'm time poor but it's interesting to to learn and now I have a "rotor" I can run some tests with.

Thanks for info Jimboot. Is your reason wanting 3-5 ohms on the coils so that you can raise voltage? To get higher coil resistance, can't you simply just use one of the four strands?

As I'm still wondering how the mix of pole count plays, did you record any frequencies, input/output?

Cool work,
