RE: [CAD_CAM_EDM_DRO] Stepper motor questions (4&6 wire) a little addendum

beware when buying second-hand 4 or 6 wire steppers, they can be 3 phase
ones, ie wire-coil-wire X3, or wire-coil-common X3 (120 degrees out of
phase, instead of the (for us) more useful 90 degrees)

Subject: [CAD_CAM_EDM_DRO] Stepper motor questions


I have been looking around at/for stepper motors.
I see that there are 4,6,8 wire motors.
Stepperworlds Controller board has connection for 6 wires.
hobbycnc board seems to work with 5,6,8 wires.
Xylotex seems to work with 4 wire.
My question is this, what is the diffrence between a 4,5,6,8 wire
motors? I would asume that each pair of wire would make up a coil
loop inside the motor. And the 4 wire motors have two loops.
and the 8 wire would have 4 loops that you would take the opposing
coil and hook up in reverse to the controler. But I'm am confussed
with 6 wire motors how would you hook these up to a 4 connector board?
If some one could explain the differnce between 4,6,8 wire motors and
how to hook them up to a 4 and 6 connector board it would add to my
understanding.....



Thanks


Jerry
