When you think about highly-precise actuators, stepper motors probably aren’t the first device that comes to mind. However, as [Diffraction Limited]’s sub-micron capable micro-manipulator shows, they ...

Bipolar stepper motors provide precise position control while operating in an open loop. Industrial automation applications—such as robots and processing and packaging machinery—and consumer ...

Open-loop stepper motors have held a prominent position in automation applications over the years due to their simplicity, excellent positioning, and low cost. However, as manufacturers utilize faster ...

Step motor control offers a powerful alternative in the right applications. Step motors are popular first and foremost because they are easy to use. They do not require an encoder to maintain their ...

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 ...

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, ...
