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… ...

This stepper motor features 8 ‘teeth’ on the stator, driven by two coils wound as two levels (top and bottom) ... Some variants also have an internal clutch, while others don’t.

Implementing internal, bi-directional current sensing inside a stepper motor driver IC results in improved motion quality with lower system cost than legacy solutions. Bipolar stepper motor basics. A ...

More specifically, permanent-magnet stepper motors include magnets on the rotor that align with the electromagnetic field moved by sequentially energizing and de-energizing stator coils.

A test and demonstration of using stepper motors in RC applications, highlighting the benefits of smooth movement and precise control compared to traditional servo motors. Includes wiring and ...

Here’s a look at servo and stepper motors’ characteristics as they relate to linear motion. (Brushless DC motors will be considered servo motors for this article.) Torque vs. Speed .
