The precise meaning of the term ‘servo’ in the context of motors and drives is difficult to pin down. Broadly speaking, if a drive incorporates ‘servo’ in its description, the implication is that it ...

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 ...

As machine builders push for higher throughput, tighter control accuracy, and smaller footprints, the selection of servo ...

When engineers think of advances in motion control technology, they usually think of faster motors, improved accuracy, or seemingly never-ending improvements in MOSFET efficiency. While these advances ...

[Chris] is at it again and this time he has put together a tutorial rounding off his animatronic face by actuating the mouth. His tutorial covers two different styles of robot mouth: an LCD mouth ...

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 ...
