Your motor has a total step of 600. It means, for a complete revolution, you have 600 steps. Hence the resolution appears to be 360°/600 = 0.6° per step. This is the resolution in what is called FULL MODE. However, your motor can works in STEP MODE 1/8. That means that you can move the motor by 1/8 of a step. Hence, you can achieve 8 more steps and thus ...

As I commented on the question, you're probably better off with conventional relays given that: their cost scales better as you go for larger/more powerful motors they are less complicated (since you stated that you've never designed a circuit before) Having said that, if you wish to pursue the solid state approach then you're probably aiming at (MOS)FETs ...

Comparing the specs of the two motors side-by-side, there are some significant differences: Model 17HS13-0404S1 datasheet Model 1704HS168A-OB datasheet Both are standard NEMA-17 size mounting plate. Both are bipolar connection. Both are rated for 12VDC operation. Specification | Model 17HS13-0404S1 | Model 1704HS168A-OB | Amps/Phase | ...
