Stepper motors are useful for relatively low-speed, intermediate-torque drive and positioning applications, particularly where accurate sub-revolution rotor position control is necessary. Motors of ...

In this chapter, I will present a few useful “cookbook” applications for real-time control circuits designed to perform some specific low-level task and interface with a master controller for ...

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 ...

Systematic methodology is the key to quickly and effectively troubleshooting control circuits. Even the most experienced troubleshooter must rely on a systematic troubleshooting process to solve ...

Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...
