This is a simple and very effective project circuit which helps to control the speed of a DC motor using pwm and microcontroller. In many applications, it is important to control the speed of DC motor ...

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.

Noctua today released its new NH-L9x65 low-profile cooler and a 4-pin PWM version of its popular NF-A6x25 60mm fan. While the latter adds PWM support for automatic speed control to the proven NF-A6x25 ...

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 ...

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 ...

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 ...

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 ...
