Withclosed loop speed control, the fan controller ensures that the fan isrunning at the desired speed by measuring the actual speed and adjustingthe duty cycle accordingly. Here the host specifies the ...

Modern processors, like those from Intel, are helping designers achieve high-performance levels from compact processors, previously unattainable, with reasonable power dissipation levels and easier to ...

In my previous article, I described the four most common methods for motor and pump control: input voltage, input voltage pulse-width modulation (PWM), external PWM, and 0–5V DC analog speed input.

This post is a quick sequel of my previous article jam-packed with my personal experiences and observations while I was fiddling with standard 4-wire PC cooling fans. Today I will be talking about the ...

This application note presents BLDC motor control using sensor sinusoidal PWM modulation with Z32F128 microcontroller. It also discusses ways on how to implement sinusoidal PWM modulation and ...

The simplest of fan-control schemes — an on-off switch — is simple but inefficient, because it provides more cooling than necessary most of the time. When on, the fully powered switch-controlled fan ...

For those of you cooling enthusiasts, you probably know Noctua by now and they make great cooling products, so when they decided to introduce their new NF-F12 PWM fan, we were more than happy take a ...
