I am working on a project for a kids museum and get to learn about stepper motors. I have taken a 4 phase 6 wire unipolar stepper motor from an old printer. http://www.mitsumi.co.jp/latest/Catalog/pdf/motor_m35sp_9_e.pdf
I was trying to use the L293D to control it. Mainly cause I ordered the chip it thinking the stepper was bipolar. I found this drawing for a 6 wire unipolar stepper... http://www.me.umn.edu/courses/me2011/arduino/technotes/stepper/coilconfig.html
Is it possible to short the two center taps and use the bipolar stepper two-wire circuit as shown in this link? http://www.tigoe.com/pcomp/code/circuits/motors/stepper-motors/ Are all 6 wire stepper motors wired the same way?
And to figure out which wire belongs to which coil, I will have to a "short" test to find out which set of 3 wires belong to each coil? Then the resistance between the coil ends should be half of the resistance between the end and the center tap?
Thanks in advance.
