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 ...

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 exhibit a special feature: the ability to rotate the rotor shaft by a few degrees very precisely and without the need for sensors to detect the shaft’s angular position. In short, a ...

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 graph shows that at 16 microsteps/full step, the incremental torque for one microstep is less than 10% of the full-step holding torque. The lure of microstepping a two-phase stepper motor is ...

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 ...

The Stepstick and Pololu motor drivers are the heart of just about every Reprap electronics board, but they can go bad. The usual way of testing these things is to rig up a microcontroller on a ...

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 ...

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 ...

Mikroe has added a smart 85V 10A stepper motor driver to its range of interchangeable ‘Click’ boards. Called Power Step 2 Click, the board “is based on the powerSTEP01, a 1/128 microstepping ...
