With positioning motion control applications, one position feedback device has been king of the hill for a long time: the incremental optical encoder with quadrature output, which has very low-cost, good-enough resolution, and good-enough ruggedness.
Brushless DC, step, and DC brush motors are the three most commonly used motor types for positioning and velocity motion control applications. Of these, brushless DC and step motors are “multi-phase,” meaning they require some type of external coil excitation. Explore the most popular techniques for multi-phase motor control, and determine which techniques work best for various positioning and high-speed spinning applications.
S-curve motion profiles add “smoothing” segments to the traditional 3-phase trapezoidal profile (accelerate, coast, decelerate). Why is this better? The answer is beyond the motor, at the load itself.
Motion controllers are complex animals, no doubt about it. But with a few tips from the experts about proper specification, location, and avoidance of mishaps, choosing the right controller for the job is as easy as one, two, three.
