Step motors provide accurate position control without the need for feedback, traditionally in open-loop control schemes. A stepper motor’s shaft normally makes discrete angular movements of ...

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 ...

Proper evaluation of torque margins across the full motion profile prevents stalling and ensures consistent performance under varying load and speed conditions. Mechanical resonance can cause ...

Available in four motor lengths and measuring 56 mm2, the Series H56S hybrid stepper motor is well suited for providing greater torque in NEMA 23 motor applications and for replacing 57-mm hybrid ...

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 ...

This application note demonstrates how increasing the slew rate of the winding currents in a bipolar stepper motor causes it to deliver more torque at high speeds. To view the application note, click ...

Ordinary printers used in daily life can print flat objects designed by computers, and 3D printers work basically the same as ordinary printers, but the printing materials are a little different. The ...

If you’ve been a good little hacker and have been tearing apart old printers like you’re supposed to, you’ve probably run across more than a few stepper motors. These motors come in a variety of ...

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.

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, ...
