Brushless servo motors – more control for valves with linear actuators

Reprint of blog posted by Ryan Klemetson of Tolomatic on Tue, Mar 24, 2015 @ 08:03 AM Many process industry control engineers are looking to more sophisticated motion control solutions for valve automation. That’s because there’s an ever-growing need to improve productivity, increase efficiency and minimize downtime. It’s essential that engineers be able to control … Continue reading Brushless servo motors – more control for valves with linear actuators

Galil Motion Controllers Support Closed Loop Step Motors

Two types of electrical motors are used extensively in automation applications: step motors with open loop operation and servo motors with incremental or absolute feedback.  The first type of application requires the motor to reach final position and hold the position.  Low cost step motors are typically used because feedback is unnecessary, and with current … Continue reading Galil Motion Controllers Support Closed Loop Step Motors

Explosion Proof Brushless Servo Motors from Kollmorgen

Based on our 230 VAC B and M Series, the Kollmorgen EB Series provides a high-performance explosion-proof servomotor suitable for applications where flammable vapors or gases create a potentially hazardous environment. These motors have been tested and proven capable of withstanding an internal explosion without bursting or allowing ignition to reach outside the motor frame. … Continue reading Explosion Proof Brushless Servo Motors from Kollmorgen

The importance of the Speed-Torque Gradient in DC Motor Sizing

Often overlooked when sizing DC motors is the Speed-Torque Gradient. The Speed-Torque Gradeint is defined as  Δn / ΔM  [rpm/mNm] . The speed / torque gradient is an indicator of a motor's performance.  The smaller the value, the more powerful the motor and consequently the less motor speed varies with load variations.  It is based on the … Continue reading The importance of the Speed-Torque Gradient in DC Motor Sizing

M is for Motion Control

Reprint of a January 19, 2013  Design World article by  Steve Meyer During the last decade or so the controls industry has adopted the term “Mechatronics” as a replacement for the previously used phrase “motion control”.    I will respectfully break with the current trend and suggest that motion control is the proper term because it … Continue reading M is for Motion Control
