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.

TENSIONING – GEARING - CAMMING - In this article we will review three widely used motion control techniques: web tension control, proportional material spacing, and CAM-based synchronized profiling.
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.

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.
Field Oriented Control (Foc), Step Motors, Servo Motors And Drives
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, including Field-oriented Control (FOC), and determine which techniques work best for various positioning and high-speed spinning applications.

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. This article talks about two common ways to implement robotic hand haptic feedback.
Robot Throughput, Automation And Robotics, Liquid Handling
In Liquid Handling Robots that are properly balanced, the gantry robot utilization reaches close to 100%, meaning the robot is almost always moving. This article (and poster) shows how we have implemented a high-speed motion system on a Liquid Handling Robot gantry that is aware of system clearances so that it can start a planar (X/Y) move while a Z-axis move is still ongoing. By employing such a motion control solution, robot move times can be improved by 25% over conventional robot moves and over 50% compared to systems that only employ single axis moves.
