He first goes over the fundamentals of a stepper motor in a practical ... Based on a clearly-explained logic table for driving the coils, a sneaky way to introduce Karnaugh maps, he proceeds ...

Stepper motors are DC (direct current) electric motors designed for precise motion control. They consist of multiple sets of coils and magnets which are designed to allow rotor movement in angular ...

So he decided to replace the stepper motor controller in his turntable and document the process for anyone else who’s scanner might be struggling. Plenty of room for expansion. In the video ...
