Potentiometers, or variable resistors, are a standard component that we take for granted. If it says “10k log” on a volume pot, than we fit and forget. But if like [Ben Holmes] you are modelling ...

SCR speed controllers that supply 180Vdc motors from 240Vac mains are wonderfully robust, but have the drawback that they always present fast-rising voltage edges to the motor’s armature at a 100Hz ...

Featuring a 1.550-in. square mounting flange, a motorized potentiometer incorporates a 200-step stepper motor�suiting applications such as shutter-control sensor applications. The potentiometer ...

The MR267 current-loop controller (CLC) optional attachment remotely controls a motorized potentiometer or rotary camswitch via 4 to 20-mA current loop, 0 to 2.5-V input, or external potentiometer.

Digitally controlled potentiometers are useful for generating analog control voltages under the control of a microcontroller. In some applications, manual pushbutton switches could replace a ...

This design idea details how a standard volume control can be replaced by its solid-state equivalent. Digital potentiometers are often advertised as replacements for rotary volume controls. To ...

Every day engineers design products that employ single-phase induction motors. Speed control of single-phase induction motors is desirable in most motor control applications since it not only provides ...
