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.

We always think it is interesting that a regular DC motor and a generator are about the same thing. Sure, each is optimized for its purpose, but inefficiencies aside, you can use electricity to rotate ...

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 ...

Trinamic Motion Control claims to be making the “smallest single-axis servo controller-driver module with integrated motion control”. TMCM-1321, as it is known, controls two-phase bipolar stepper ...

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 ...

Allegro MicroSystems has announced a new integrated bipolar stepper motor driver IC with built-in translator for easy operation. Allegro MicroSystems has announced a new integrated bipolar stepper ...

TRINAMIC extends its portfolio of TMCM embedded motor control modules. Following the success of the TMCM-351 triple axis board, the TMCM-3351 is designed to be as easy to use as its sibling, but with ...

The new PJE series of bipolar hybrid stepper motors from Nippon Pulse America Inc. are available in sizes from 20 to 86 mm in diameter (NEMA sizes 8 to 34). The motors provide high torque in each of ...

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 ...

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.
