How to Select a Direct Drive Linear Actuator >
There are several considerations when selecting a direct drive linear actuator for a specific application, such as the required speed, force, motion profile, available physical envelope, and environmental factors. This means the chosen actuator…
How Does Kollmorgen Utilize Data Analytics for AGVs? >
The purpose of an AGV system is efficient transportation of goods in a specified environment. The AGV system is a big investment, so it is desirable to have a high degree of utilization as well as a high ratio of deliveries per hour to get a good…
How Does a Direct Drive Linear Servo Motor (Actuator) Work? >
A direct drive linear actuator, using a permanent magnet linear servo motor produces force and velocity based on the supplied current and voltage and provides a linear movement along the axis being driven. The linear servo motor works as part of a…
Disrupt Automation with User Experience Design >
Companies working toward the consumer market have long invested in and understood the value of user experience (UX) design. A good user experience is a key differentiator in today's market, and by aligning your company to ensure that your customers…
Bandwidth, Gain and Phase Margin in Servo Systems: What is Phase Margin? >
Phase margin is a measurement in the frequency domain, taken from a Bode plot, that calculates the amount of phase lag above -180 degrees at the point on the amplitude plot that crosses 0dB (gain cross over frequency).
EasyEngineering Interview with Peter Bladh, Director Research & Development >
Kollmorgen Automation is part of Kollmorgen, which in turn belongs to the NASDAQ-listed Altra Industrial Motion group. The company develops and sells products and services related to automation solutions for applications that include warehousing and…
Bandwidth, Gain and Phase Margin in Servo Systems: What is Amplitude Gain Margin? >
Amplitude gain margin is a measurement in the frequency domain, taken from a Bode plot, that takes the amplitude below 0 dB at the lowest frequency point that the phase reaches -180 degrees (phase crossover frequency).
How to Select a Servo Drive >
A servo drive should be selected based on the specific servo motor used in the application. Find out ho to select a servo drive for your application.
Bandwidth, Gain and Phase Margin in Servo Systems: What is Bandwidth? >
In simplified terms, bandwidth can be calculated as 1/(settling time) of a given step response of a servo system.
How Does a Servo Drive Work? >
A servo drive is an electronic device that is part of a closed loop system, producing current and voltage to rotate a servo motor. The closed loop system includes the servo drive, servo motor and feedback device, and is commanded from an analog or…
Four Key Values to Determine Servo System Stability >
A stable servo system is essential for optimal machine performance, durability, safety, and consistent machine performance, which improves overall machine operation. Servo systems operate in various degrees of stability, with a fine line between…
