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 ...

In this exciting video, we dive into the world of controlling high voltage DC motors and the intricate process of designing a ...

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 ...

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 ...

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 ...
