Stepper motors are brushless synchronous electric motors powered by direct current that rotate in steps, keeping the rotor stationary under a specific power supply. A well-defined sequence of PWM ...

Stepper motors divide a full rotation into hundreds of discrete steps, which makes them ideal to precisely control movements, be it in cars, robots, 3D printers or CNC machines. Most stepper motors ...

Here's a simple algorithm that uses conventional microcontroller blocks to control commercially available H-bridges to properly commutate a bipolar stepper motor through a microstepping profile.

The A4979 is a flexible microstepping motor driver with built-in translator for easy operation. It is a single-chip solution, designed to operate bipolar stepper motors in full-, half-, quarter- and ...

Microstepping a two-phase stepper motor requires the winding currents to be 90° out-of- phase so that the stepper functions like a synchronous motor with ac applied. That is, the phase A current is ...

Toshiba Electronics Europe has introduced a new stepper motor driver integrated circuit, the TB67S579FTG, featuring its next‑generation Advanced Microstep Technology aimed at improving efficiency, ...

A new microstepping motor driver IC utilizes the EasyStepper translator for microstepping (one-eighth step) operation. The A3967 motor driver IC complements the company’s stepper motor product line by ...

Know the four most common microstepping myths. Myth 1: A high microstep count will result in evenly spaced steps at that count. Microstepping is good for smooth motion. However, having a 256 microstep ...

Many step motor users are faced with a question of whether or not to use microstepping in their stepper motor application. “What will it affect and how will I benefit from it?� one may ask.

Even veteran engineers often suffer from a lot of misconceptions about stepper motors and how to drive them. This article will focus on clearing up just a few of these misunderstandings so that ...
