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 ...

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 ...

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

Embedded exhibition sets out to simplify DC motor control circuits Richard Wilson Simplifying the design of DC motor control circuits was the aim of a number of microcontroller announcements at last ...

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 ...

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!
