Hi.
I want to do some testing with salvaged stepper from a harddisk (samsung) wich has 4 wires. But I thought that 4 wire are bipolar steppers and those have 2 coils wich do not cross leads.
This stepper has the wires labeled as A, B, C and CT and Ive tested them with a digital ohm meter and get :
A-B : 4 Ohm
A-C : 4 Ohm
A-CT : 2 Ohm
B-C : 4 Ohm
B-CT : 2 Ohm
C-CT : 2 Ohm

Is this right for a bipolar stepper?

Any coments on this motor?
