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 ...

The project drives a bipolar stepper motor with the use of a dual H-bridge IS such as the SN754410. The bipolar stepper motors are usually identified on most steppers with 4 wires. Measuring the ...

There are a lot of fun projects you can do with stepper motors salvaged from old printers or disk drives. However, it isn’t always clear how to connect to some strange motor with no markings or ...

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 A3982 is a bipolar stepper motor drive with DMOS outputs rated at 35 V and ±1.5 A (2 A peak). Higher motor currents and reduced temperature rise come from low on resistance DMOS outputs and ...

Bipolar stepper motors are used in many applications, from driving paper through a printer to moving an XY stage in industrial equipment. Typically, the motors are driven and controlled by inexpensive ...

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 ...
