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!

Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

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 ...

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 ...

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 ...
