How do you wind this driver? I assume both coils are wound together in parallel, so if they are connected in
series (or parallel), they would perform as a regular single-coil driver, right? Also, if you build such driver, wouldn't
you need to test it first to see at least that it is good electrical parameters-wise before commiting to a big batch?
What kind of driver would you use for this out of your product range?
Thanks,
