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 ...

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 ...

Motor controllers in general and especially closed-loop controllers have come a very long way in the past few years. Control flexibility, adaptability, and strategies that were only dreamed of or very ...

This file type includes high-resolution graphics and schematics when applicable. Millions of small electrical devices with built-in motor-driven mechanisms, used daily around the world, rely on ...

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.

If you are building a project that needs to control stepper motors wirelessly you might be interested in a new piece of hardware created by the team at Good Robotics which takes the form of the aptly ...

The primary feature of stepper motors is listed right within their name: their ability to ‘step’ forwards and backwards, something which they (ideally) can do perfectly in sync with the input provided ...

Stepper motor linear actuators (SMLAs) combine a stepper motor, precision lead screw and nut in one compact envelope, providing a highly configurable, customizable and robust system for linear motion.
