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 ...

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 ...

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 ...

Many step motor users are faced with a question of whether or not to use microstepping in their stepper motor application. “What will it affect and how will I benefit from it?� one may ask.

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 ...

Stepmotors and servomotors are both used successfully for positioning in equipment worldwide. However, designers sometimes overlook their distinct characteristics. The two motor types offer different ...

Stepper motors resemble servo motors in that both types are characterized by an ability to rotate a partial turn and then stop for any interval with or without holding torque. In addition, both motor ...

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, ...

Several different styles of stepper motors in different NEMA sizes. CNC machine centers offer many benefits over manual machining such as greater productivity, precision production, and reduced labor ...

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.
