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, ...

Encoders are integral parts of motor-control systems that sense mechanical motion, then generate digital signals in response to that motion. The trend today is to create smaller mechanical and ...

The leading and longest established online Process Engineering publication serving the Process Manufacturing Industries ...

To attain accurate positioning, a servo system requires a feedback signal to close its feedback loop. Instruments that typically supply the feedback signal include optical encoders, resolvers, and ...

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 ...

Today, we shall talk about how [Adam Bäckström] took a DS3225 servo and rebuilt it to improve its accuracy, then built a high-precision robot arm with those modified servos to show just how much of an ...

The 1FK7 servo motor from Siemens is developed with field-replaceable encoders that make for quick and easy on-site service with no special tools or recalibration required. Automation World covers the ...

For engineers seeking a motor scaled down in size but not power, QuickSilver Controls has extended its Mosolver (portmanteau of “motor” and “resolver”) servo motion actuator into a NEMA 17 frame ...

Pittman Motors, a unit of Ametek Precision Motion Control, offers IP65 industrial grade servo motors that are ideal for use in harsh industrial applications. Pittman Motors, a unit of Ametek Precision ...
