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 ...

Say the word “analog” to most EEs, and thoughts turn to op-amps, power devices, I/O, or signal conditioning circuits. But, the system beyond the circuit is also full of “analog,” if we include ...

When grounding exposed non-current-carrying metal parts of motors and controller frames to prevent a voltage above ground in the event of accidental contact between energized parts and frames, what ...

For electricity to flow, everything needs to be connected in a big ring. It’s called a circuit. For example, the lights in most houses and flats are part of a circuit controlled by the consumer unit, ...

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 ...

Motor skill learning involves changes in the motor cortex observed at several levels 1,2,3,4,5,6,7,8,9. At the structural level, motor learning has been shown to induce reorganization of dendritic ...

When building a dedicated race car for competition use—one that will always be trailered and never be used on the street—it’s imperative that the wiring system not only be kept simple but be easy to ...
