Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to spin at a rate per unit ...

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 ...

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 ...

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 ...

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.
