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 ...

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 ...

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 ...

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 ...

Improved microstepping accuracy, and lower motor audible noise and heating results from advanced techniques for current management. Stepper motor motion systems, formerly relegated to low-speed, high ...

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 ...

In theory, you really don’t need much to work with electronics. A scope ought to do everything. However, for special purposes, it is handy to have meters, logic analyzers, and other special-purpose ...

It’s increasingly common for designers to pair stepper motors with motion-control SoCs. In fact, more design engineers than ever are setting up SoCs themselves for motion applications. These chips ...
