Re: [CAD_CAM_EDM_DRO] Please help...3 phase Stepper motor translator

Hello,

is this not just a brusless DC. You need to drive it
like a three phase motor. First current in windings 1
& 2, then in 2 & 3 and the in 3 & 1. It all start over
back to 1 & 2

This swas the full step, in half step you ativate :

1 & 2
2
2 & 3
3
3 & 1
1
and back to the first 1 & 2

But are you sure the black is common. A two phase
stepper also has 4 wires.

Try a search with google, there are loads of tutorials
on haw steppers work.

Hope this helped,
Groenwed
