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 ...

This file type includes high resolution graphics and schematics when applicable. This 8051 microcontroller-based control circuit adjusts the speed of a small permanent-magnet dc motor via photosensors ...

Movement is a complex process governed by a network of neuronal circuits spread across multiple regions of the nervous system ...

Writing, driving a screw or throwing darts are only some of the activities that demand a high level of skill. How the brain masters such exquisite movements has now been described. A map of brainstem ...

Here is a motor speed sensor module, the major goal is to check the rate of an electric motor. The module can be used in association with a microcontroller for motor speed detection, pulse count, ...

One maintenance task that’s often overlooked is the monitoring of harmonics in motor circuits. Typically, high harmonic content goes unnoticed until someone decides to investigate power quality as a ...
