This application note describes how to implement an exact linear speed controller for stepper motors. The stepper motor is an electromagnetic device that converts digital pulses into mechanical shaft ...

This Design Idea further develops a previous one integrating a stepper-motor driver in a CPLD (Reference 1). However, this idea integrates not only the driver, but also a simple one-axis stepper-motor ...

Agile Systems has received a patent for technology designed to improve stepper-motor performance. It allows simple low-cost two-phase stepper motors to operate as sophisticated servo motors without ...

This file type includes high-resolution graphics and schematics when applicable. Millions of small electrical devices with built-in motor-driven mechanisms, used daily around the world, rely on ...

3D scanners aren’t cheap, and the last thing you want to see after purchasing one is bad data. But that’s what [Dave Does] and others were getting from their Revopoint POP scanners until some communal ...

Not missing a beat: Here we take a look at why open-loop steppers lose steps, as well as some solutions to the problem. As in the below) half-stepping produces eight steps per electrical rotation — ...
