In between, when I 1 /I 2 = 0.4142, which we dubbed the half-excitation state, the stepper motor advances in a 16-step sequence and moves 1600 steps per revolution.

The [Denki Otaku] YouTube channel took a look recently at some stepper motors, or ‘stepping motors’ as they’re called in Japanese. Using a 2-phase stepper motor as an example, the… ...

Typical stepper-motor control circuits use either logic gates and flip-flops or shift registers to generate the proper sequences of binary codes that produce bidirectional stepper-motor movement. A ...

If we follow this sequence, the motor moves in one direction. If we now reverse the same sequence, the motor moves in the opposing direction. Click on image to enlarge. Figure 3. The typical ...
