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!

Another intriguing issue is whether circuits in the remaining frontal agranular cortex—presumably involved in more ‘cognitive’ aspects of motor control—are organized in the form of primary motor ...

A seemingly trivial circuit layout can be problematic because of the higher than usual currents that are common in motor-control circuits. Although the circuits that monitor three legs are slightly ...

Electrical Power and Control’s new guide explains how motor starters safeguard industrial systems, highlighting safety, ...

The latest microcontrollers featuring field-oriented control bring higher efficiency to motor-control circuit designs in consumer ...

Guest columnist Alfred Hesener, European marketing director at Fairchild Semiconductor, describes how good design of power switches can help reduce losses in motor control circuits. Energy-saving ...

Groomed for use in small-motor control circuits, the HSF series surface-mount, surge resistor exploits a cylindrical design to aid heat dissipation and produce higher surge/pulse capabilities than ...

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 ...

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 ...
