The [Denki Otaku] YouTube channel took a look recently at some stepper motors, or ‘stepping motors’ as they’re called in Japanese. Using a 2-phase stepper motor as an example, the stepper motor is ...

Allegro MicroSystems, Inc. introduces a new motor driver IC designed to drive one winding of a bipolar stepper motor in a microstepping mode. Allegro MicroSystems, Inc. introduces a new motor driver ...

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 ...

Monolithic power ICs that are physically small, inexpensive, practical, and programmable can replace the bulkier, less flexible and more expensive boards and boxes that provide microstepping ...

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.

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.

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 ...

The new Compumotor-brand Open Frame Stepper (OFS) microstepping drives are an alternative to ac-powered step drives, especially for less-demanding point-topoint applications. The drives feature ...

Allegro Microsystems had released a full-bridge PWM microstepping motor driver last 2013 that features an output of ±1.5 A continuous current with a 50 V voltage rating, the A4975. This device is ...
