General Purpose Permanent Magnet Motor Drive without Speed and Position Sensor
By Jun Kang, Yaskawa
PM AC motors have many advantages versus induction motors including compact size, high efficiency, less weight, and high torque. A speed sensor has been one of the main obstacles that slow down the spread of PM motor drives for general-purpose applications because it is expensive and not reliable. This article describes a good solution for applications that need high-efficiency features of PM motors or high-dynamic speed control features of IPM motors even at low speeds without a speed sensor.

The New Kollmorgen Engineer’s Library
By Kollmorgen
One definition of an engineer is someone who’s always curious about the way things work, and how to make them work better. Just for those people, we’ve created a new Engineer’s Library, with resources to help you envision, design and realize a better machine. First up, we have three white papers on servo drive technologies, full-frequency auto-tuning and solutions for flexo printing. We’ll be updating the Engineer’s Library several times per year, so check in often.

Fluid Automation: Unsung Contributor to Plant Performance
By ASCO Numatics
Fluid automation systems do more than control the flow of a process liquid or compressed air. Perceptive managers know that valves and pneumatic actuators can control the flow of profit. This management brief explores how fluid automation’s speed and reliability can provide competitive economic advantages in plant operations worldwide.
