The speed of a DC motor is directly proportional to the voltage applied across its terminals. The speed of a DC motor is directly proportional to the voltage applied across its terminals. This project ...

This is yet another project born of necessity. It’s a simple circuit, but does exactly what it’s designed to do – dim LED lights or control the speed of 12V DC motors. The circuit uses PWM to regulate ...

The 555 timer IC is a handful of active components all baked into one beautifully useful 8 pin package. Originally designed for timing purposes, they became ubiquitous parts that can achieve almost ...

Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...

With time on my hands, I decided to try a technique that I noticed first in a L200 voltage regulator data sheet. It is fig 25 in STM’s ‘A Designer’s guide to the L200 voltage regulator’ (ST webpage ...

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 ...

The high performance AXU Series brushless speed control systems can maintain a constant torque value over the entire speed range of 100rpm to 2000rpm. These compact packages are composed of a BLDC ...

Maxim has introduced a bi-directional current sense amplifier with pulse-width modulation (PWM) edge rejection. Called MAX40056 it is intended to reduce vibration in motor drives. The claim is that it ...
