The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...

A brushless-DC motor is common in ceiling fan and pan-tilt-zoom (PTZ) camera designs. But you can’t use the same brushless-DC motor solution for both of these end products. A ceiling fan driver ...

When implementing cooling solutions for electronic equipment, system designers are confronted with a complex set of variables. The cooling requirements are typically dynamic, and ambient temperatures ...

New motor driver ICs focus on ultra-low standby power, flexible H-bridge configurations, and reduced external components to support compact consumer and industrial motor control applications.

Startup techniques employed to overcome the problem of determining magnet position in BLDC designs. Cost-saving and power-efficiency incentives using sensorless motor drivers. Motor-driver solutions ...

A few weeks ago, I saw a reader’s question about how to run PS3 cooling fans using an external electronics circuit. At the time I was busy with some other projects. The other day, I decided to put my ...
