Well, I guess I have to figure out how to drive the damn thing first. There are only 5 wires...red, green, blue, black, and orange. I'm not sure if I need H-bridges or half-bridges or what.
will those PNP and NPN BJTs be fast enough to switch at like 10kHz directly off a microcontroller (50kHz is needed for 60rpm on this motor)?
What kind of motor is this?
Where did it come from?
Is this some sort of specialty motor?
Is it really .0072 deg/step without microstepping?
How you you know it will do 50 KHz?
That also seems extraordinarily unlikely
