RE: [CAD_CAM_EDM_DRO] Stepper motor questions (4,6,8 wire motors)

inside all the mentioned stepper motors there are (essentially) 4 coils. If
you bring all the coil ends out, you have 8 wires (wire-coil-wire, X4), if
you connect pairs of coils in series and bring out a common centre
connection from each pair, you have 6 wires, (wire-coil-wire-coil-wire X2)
and if you don't bother connecting the middle of the pairs you have 4 wires
(wire-coil-coil-wire, x2). Draw it!.

Usually, connecting a 6 wire stepper to a 4 wire controller, you don't
connect the centre taps.

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
