Hi.
So i had a couple stepper motors laying around. I got them from a couple printers and i wanted to make a little discrete transistor stepper driver so i could hook my µcontroller to play around.
I tried doing something on LTspice but couldn't get it to work ( it did do something though ).
The motor i'm playing around with right now has four wires coming out of it but there is no common wire, it has a sticker on the side saying 7.5 deg/step and 7.0 ohms. I measured the wires and it seems like it does indeed have two coils with 7 ohms of resistance.
I want to make a simple circuit with about 3 transistors driving each wire, i want the wire be grounded unless there is about 3-5V on the input side of the driver transistor array/thing.
As i said i did try doing it on LTspice but i didn't get anything worth showing ( transistors dissipating terawatts, yeah...
).
I'd appreciate some if any help.
