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 ...

Many applications using miniature brushed DC motors require motors to operate at more than one load point or through specific load cycles. Running a motor at usable load points requires a variable, ...

H Bridge configuration is commonly used in electrical applications where the load needs to be driven in either direction. A typical H-Bridge structure is shown below; The current flows through the ...

Maxon Precision Motor's newly released DC servo motor controller, the ESCON 50/5 OEM module. This mini OEM plug in module is a 4 quadrant Pulse Width Modulated (PWM) servo motor controller that can ...

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 ...

Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...

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 ...
