The fundamental circuit shown in Figure 1 generates timing for a two-phase stepper motor from an oscillator, as well as a direction (forward or reverse) signal. Figure 2 depicts the typical timing ...

This article presents the stepper motors as a technology creation and technology enabler in the modern era of electronic products. It describes the basics of stepper motor, the attributes, the ...

Stepper motors produce accurate, computer-controlled motion for applications such as robotic arms and paper-feed mechanisms for printers. They require current pulses delivered through a special ...

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

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 ...

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 ...

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 ...

In 1960, the large-angle type PM step motor was the most used step motor. This two-phase, bifilar wound PM step motor (top) advanced 45° mechanical with each pulse from the drive, while by 1962 PM ...

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.
