• 8 Tips for Minimizing or Eliminating EMI Noise

    June 21, 2012, by Bob White

    Noise, and I'm not talking about that terrible band you heard at the summer fest last year, but electromagnetic interference (EMI) noise. There are 8 key steps to consider when trying to eliminate EMI noise issues. If you follow these guidelines, you are much less likely to have problems with electrical noise in your application.

  • Something is Missing...and other Linear Actuator Nightmares!

    November 19, 2013, by Michael Brown

    A specification will often state the required stroke for the application. What is frequently seen is that units are damaged by not following a simple requirement stated in the Installation Manual. Best practices dictate the utilization of End of Travel (EOT) sensors used with actuators and drives. This is done to prevent the actuators from striking the mechanical stops at each end, and typically a manual will clearly show where these sensors should be placed on the device. Actuators do have built in "bumpers" to help absorb energy when the mechanical stops are struck, but they are not designed to provide unlimited protection against repeated strikes.

  • Switched at Birth: Motor Winding Nomenclature Explained

    If you have been following along on our Evolution of Kollmorgen posts, you realize Hugo Unruh was one of the first to successfully commercialize frameless motor technology. What most people don't realize is that Kollmorgen's motor-drive phase identification standards (A, B, C) were based on these frameless motors. Now the issue at hand is both sides of a frameless motor typically look the same, except for the side where the wire leads exit.

  • Ethernet Networks Simplified

    Setting up an Ethernet network can be frustrating if you don't understand the basics. A network is just the communication connection between two or more devices. These devices can be computers, PLC's, servo drives, HMI's, sensors, cameras…anything that supports Ethernet communication.

  • 3 Key Reasons for NOT Taking Shortcuts for Motor Repairs

    February 02, 2015, by Paul Coughlin

    Brushless AC servo motors stepper motors have long life spans, which are largely due to the lack of wearing components. Unlike brush type motors, other than the bearings, brushless AC servo motors and stepper motors have no wearing components. Additionally you do not have conductive brush dust, which, as it collects on the commutator, may short the armature. The radial and axial loading requirements of step and servo motors are based upon the shafts of the motor, which are usually far less than what the bearings are designed to handle, which provides for a healthy motor life span. However, occasionally motors do need to be repaired.

  • Getting the Best Performance from Encoders

    February 09, 2015, by Application Team India

    I often see some confusion in various customers’ minds regarding encoder performance with automation systems which have servo drives or variable frequency drives (VFD). Some customers feel that when they are providing best in class encoders, the system must be highly accurate.

    Sounds logical? … Yes, but there are some other points to consider also.

  • Tips on How to Confidently Set Up Your Linear Motor System

    February 03, 2016, by Bob White

    Linear motors fill an important role in providing a robust and high precision direct drive solution in many high performance applications. In order to achieve the highest level of performance, the linear motor system must be commissioned properly. This blog post addresses key areas to consider when setting up and commissioning a linear motor system. It is always important to refer to the installation and set -up instructions provided by the manufacturer.
