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!

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 ...

Reversing Motor Circuits provides a comprehensive overview of the various means used to reverse electric motors. Motor control circuits use various control devices to change the direction in which a ...

In this online engineering specialization, you will master sensor and motor theory and program these devices in a microprocessor system. You will complete courses in sensors and sensor circuit design; ...

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 ...

TT electronics IRC Wirewound and Film Technologies Division recently introduced a surface-mount high-surge resistor for use in small motor control circuit designs in automotive and industrial ...

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 ...

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 ...
