circuit design of 4-wire bipolar motor COILS
Posted: Tue Apr 13, 2010 9:29 pm
hello,
I'm taking apart a stepper motor (just like the one on the sparkfun page: Stepper Motor with cable sku: ROB-09238) and I need to know how the 8 coils of wire are connected.
The stepper motor is a 4-wire bipolar motor, but it's got 8 coils inside it. I want to cut the wires so that i can send current within each of the coils individually, but it's really hard to see which wires are coming from which (very limited viewing). (that is, I don't want to have to unravel each coil).
Does anyone know how the coils are connected up?
thank you,
veritas
