Unipolar vs. Bipolar drive for stepper motors, Part 2: Tradeoffs
Stepper motors can be configured for unipolar or bipolar drive; each approach has different performance attributes and tradeoffs. The previous part of this article presented the basics of different coil windings and connections for unipolar and bipolar stepper-motor configurations. As in most engineering situations, the next questions are: what is the impact of these differences? […]
Unipolar vs. Bipolar drive for stepper motors, Part 3: Drive ICs
Stepper motors can be configured for unipolar or bipolar drive; each approach has different performance attributes and tradeoffs. Despite their usefulness and suitability of stepper motors for precision positioning, especially in back-and-forth motion applications, one of the factors which delayed their widespread adoption was the challenge of providing the needed driver management. However, the introduction […]
Unipolar vs. Bipolar drive for stepper motors, Part 1: principles
Stepper motors can be configured for unipolar or bipolar drive; each approach has different performance attributes and tradeoffs. Stepper motors are widely used, and, as with so many basic components, they are simple in some ways but also have multiple configurations and operating subtleties. For steppers (the “motor” part of the two-word term is often […]
