Frequently, when it comes to step motor selection, users will select a motor with the highest holding torque rating, assuming that it will give them optimal performance. However, it is an improper ...

When you think about highly-precise actuators, stepper motors probably aren’t the first device that comes to mind. However, as [Diffraction Limited]’s sub-micron capable micro-manipulator shows, they ...

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 ...

Stepper motor systems are highly efficient when producing torque, but lack operational efficiency when not producing torque. Applied Motion Products offers insights on how to make a greener and more ...

The world is digital today, and most information is represented in numbers. However, human nature is more “analog” and better represented in the old-fashioned way, using pointer gauges and bar graphs.

Stepper motors are often used for positioning since they are cost-effective, easy to drive, and can be used in open-loop systems—meaning that they don’t require position feedback like servo motors.

Sometimes less is more. Here, a quarter-step switching logic sequence for stepper motors offers several significant advantages over full-and halfstep modes—higher resolution, smoother drive, minimal ...

Adjust the phase current, crank up the microstepping, and forget about it — that’s what most people want out of a stepper motor driver IC. Although they power most of our CNC machines and 3D printers, ...
