Step Motor, Stepper Motor Drive Circuit, Closed Loop Motion Control
Step motors are a common solution for controlling the position of moving components, but in some cases can be inadequate since the motor position is not necessarily known. Even though step motors are inexpensive when compared to brushless motors, in many critical applications, care has to be taken to ensure that when a command is given to the step motor controller, the motor actually ends up where the user wants it to go. In this article, we will look at each motor control design option and provide an in-depth review of a new closed loop motion control system.
Everyone who has worked in motion control has a war story, be it the machine that mysteriously stopped working or the motor that wouldn't stop vibrating. Fortunately, common problems often have common solutions.
We continue with our deep dive series that gives you tools to diagnose common motion control problems and get your machine back on track!

Conventional step “current chopper” drives result in a large amount of step motor noise, needless motor heating, and consume more current. A digital current loop will result in significantly quieter and lower temperature motor operation which is beneficial in many applications. This article details how a digital current loop will result in a significantly quieter, faster running and lower temperature motor operation which is beneficial in many applications.
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.
Motion Control In Robots, Advanced Motion Control
Motion control applications with an operator remotely controlling a robot hand or mechanism can now be expanded to where the operator can “feel” what the robot is touching.
Several trends have been driving the use of sophisticated, complex motor control algorithms. The most important of these trends include the desire for lower energy consumption and the need for higher performance. Performance Motion Devices Founder Chuck Lewin addresses these trends and introduces the major techniques used to control multi-phase motors, both brushless DC and AC induction.
