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 ...

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.

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 ...

Find a downloadable version of this story in pdf format at the end of the story. A new controller IC, the L6470 for stepper motors, integrates the power stage along with a digital control core on a ...

Microstepping is a major advancement in step motor technology introduced many years ago that allows motors to make finer steps in movement. By manipulating the current vector, microstepping creates ...

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 ...

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 ...

Toshiba Electronics Europe has introduced a new stepper motor driver integrated circuit, the TB67S579FTG, featuring its next‑generation Advanced Microstep Technology aimed at improving efficiency, ...

Motion Control Products Ltd is launching the DMD556 next-generation digital microstepping drive that is claimed to benefit from unprecedented audio noise reduction (by 70%) and smooth low-speed ...
