In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...

In this guide, we introduce a custom-built Wireless Stepper Motor Controller with ESP32, a simple yet powerful way to add Wi-Fi stepper motor control to any project. This wireless stepper motor driver ...

When you get the call, “The motor won’t start,” you’d best have a logical and systematic plan in place to approach the problem. “Easter egging” just doesn’t work unless you happen to be very lucky!

Block diagrams close block diagramA diagram of a system represented by blocks connected by lines. are clear, simple diagrams showing all of the input, process and output elements that make up the ...

Motor control and drives are fundamental in many applications, as they allow a high degree of accuracy, which in turn translates into lower costs and greater efficiency. The vital function performed ...

I was planning to use the opto-coupler speed sensor as part of a motor speed control – making the motor into the VCO block in a phase-locked loop. When this technique works, using it is simple: put ...
