Stepper motors produce accurate, computer-controlled motion for applications such as robotic arms and paper-feed mechanisms for printers. They require current pulses delivered through a special ...

This application note describes how to implement an exact linear speed controller for stepper motors. The stepper motor is an electromagnetic device that converts digital pulses into mechanical shaft ...

Given their ubiquity, it is no surprise that embedded systems designers devote a lot of imagination to coming up with innovative ways to make MCU-controlled steppers and microsteppers do more and do ...

This project implements speed and direction control of a DC motor using an Arduino Uno and an H-Bridge motor driver (L293D). The system allows the user to control the motor rotation direction using ...

Project Objective The objective of this project is to control the speed of a DC motor using Pulse Width Modulation (PWM). An NE555 timer is used to generate a variable-duty-cycle PWM signal, which ...

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 ...

Stepper motors are pretty easy to control with a microcontroller. But if you’re looking to run then at a high number of revolutions per second things get tricky pretty quickly. [Uwe’s] been learning ...

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 ...

This article describes ongoing internal project activities at eInfochips in the control systems domain for applications in motor and engine controls aimed for aerospace and automotive segments.
