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 ...

Find a downloadable version of this story in pdf format at the end of the story. Microstepping a two-phase stepper motor requires the winding currents to be 90° out-of- phase so that the stepper ...

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.

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.

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 ...
