Why get up close and personal with a resistor when you can tweak it from a distance? Remote variable resistors make analog circuit control easier, neater, and a lot more fun. Well, we are about to ...

Variable frequency drives (or VFDs) are widely used throughout industry to provide adjustable speed control of ac motors. Although modern versions are relatively simple to install and operate, VFDs ...

Combined with productivity and associated reliability costs, a motor circuit analysis program can justify itself immediately. In recent years methods for controlling energy costs have evolved from a ...
