In this article we will discuss how to build a powerful DC motor driver that can be controlled using a microcontroller like an Arduino or a Raspberry Pi, or even a standalone PWM generator chip. DC ...

The company was early into adding phase-locked loop clock multipliers to give the PWM machinery something faster than the processor clock to work with. Arduino offers a simple framework to programme ...

Among all the Arduino boards, the Uno is most folks' go-to choice, and for good reason. It's the perfect platform to get started with Arduino, it's capable enough to handle a wide range of tasks, and ...

This application note presents Z16FMC microcontroller used to control 3-phase brushless BLDC motors in a sinusoidal PWM modulation mode. It discusses the ways in which to implement sinusoidal PWM ...

Brushless motors are ubiquitous in RC applications and robotics, but are usually driven with low-cost motor controllers that have to be controlled with RC-style PWM signals and don’t allow for much ...

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, ...

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 ...

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.

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 ...
