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 ...

Action and perception are functionally linked in the brain, but a hotly debated question is whether perception and comprehension of stimuli depend on motor circuits. Brain language mechanisms are ...

The developmental source for a key type of neuron that allows animals to walk, a finding that could help pave the way for new therapies for spinal cord injuries or other motor impairments related to ...

To prevent a motor from burning up, you must provide a means of protecting it from overcurrent (overload, short circuit, or ground fault). If you can remember not to confuse motor protection with ...

The PCA146x series devices are CMOS integrated circuits specially suited for battery-operated, quartz-crystal-controlled wrist-watches, with a bipolar stepping motor. The motor output delivers pulses ...

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 ...

While research has demonstrated that stress can impact immune function, the exact mechanisms by which these alterations occur in the brain remain unknown. A new Nature study explores how acute ...

Controlling a small dc motor without speed control sounds like a trivial task; a switch or a relay should suffice. However, several problems accompany this approach. For one, the switch, because of ...

The new Allen-Bradley Bulletin 140MT motor protection circuit breakers from Rockwell Automation offer enhanced Type F combination motor controller ratings when used with Bulletin 100-C and 100-E ...

Father of Lotus, Colin Chapman, said his secret to engineering racing and sports cars was to "add lightness." An intriguing phrase, to say the least. And one that might well have been lost in time by ...
