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 ...

Stepper motors find use in many automotive applications,including headlight leveling; adaptiveheadlamps, in which the headlamps turn rightor left with the steering wheel; EGR ...

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 ...

Bipolar stepper motors are used in many applications, from driving paper through a printer to moving an XY stage in industrial equipment. Typically, the motors are driven and controlled by inexpensive ...

The primary feature of stepper motors is listed right within their name: their ability to ‘step’ forwards and backwards, something which they (ideally) can do perfectly in sync with the input provided ...

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 ...

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.

It is an engineering truism that there is no such thing as a perfect solution—just the best solution for the problem at hand. That holds particularly true for servo motors and stepper motors. Both are ...

Stepper motor linear actuators (SMLAs) combine a stepper motor, precision lead screw and nut in one compact envelope, providing a highly configurable, customizable and robust system for linear motion.

The International Electrotechnical Commission (IEC) defines a servo device as “an adjustable-speed AC power drive system that includes an AC motor integrated by feedback, a converter, and control, ...
