New micros simplify digital current-mode control, letting step motors run faster, smoother, and with greater precision. For the last 40 years, stepper motors have been used in applications requiring ...

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 ...

Step motors are a natural choice when design specs call for low-cost automation with accurate, open-loop control. But finding the right stepper for a given application can be a challenge. There’s a ...

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, ...

Increasingly elaborate Rube Goldberg schemes for controlling step-motors have developed over the years that try to pace stepping to avoid missteps. This direction of development is fundamentally ...

In a recent article, I wrote about step-motor system performance emphasizing key concepts that all engineers need to understand about this widely-used electro-magnetic-mechanical digital actuator. As ...

When it’s time to specify a high-performance motor that offers both precise positioning and cost efficiency, stepper motors offer many advantages over DC motors thanks to their brushless technology.

The Series H42S high-torque, 42-mm. hybrid step motor has improved performance and competitive pricing. The 1.8 deg. step motors--measuring 42 mm. square--are available in four lengths: 25, 34, 40 and ...

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 ...

TRINAMIC Motion Control's new TMC2660 stepper motor driver IC supports motor drive currents up to 4A. The new IC integrates both a pre-driver for real-time calculation of motor coil current values, ...
