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 ...

From single-cable systems to energy-harvesting encoders, new feedback device features improve accuracy, reduce downtime and ...

Encoders are widely used in the motion control and automation industry to monitor the position and speed of motors. This information can be used by the motion control electronics to detect if the ...

Quantum Devices Inc. recently announced a new series of miniature incremental optical encoders. Each of the encoders in the QM22 series has a 22-mm diameter and 12.4-mm thickness. According to the ...

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 ...

Usually, when you want a servo motor, you simply buy one already made. But if you need something unusual, you can turn any DC motor into a custom servo you can control just like [Dejan] did. You can ...

While current control and PWM switching play the most direct role in driving brushless DC motors, the motion profile and ...

Targeting brush motors running at less than 100W with quadrature encoders, the 3C20 digital-motion controller claims a 32-bit or greater precision in position, velocity and acceleration, and jerk ...

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 ...
