Getting a magnetic field to balance on another magnetic field is about as easy as balancing a bowling ball on the tip of an ink pen. With a little help from an Arduino mega, however, [EmmaSong ...

The Hall effect sensor monitors the field of the permanent magnet and uses that information to modulate the magnetic field of the electromagnet, with everything being crunched by the Arduino.

When it comes to rotary encoders, there are plenty of options. Most of them involve putting a credit card number into an online vendor’s website, though, and that’s sometimes just not i… ...

Designed without gears to eliminate wear and sensitivity to magnetic fields, the Kübler by TURCK F36 optical encoder series features a compact size of only 36 mm with a hollow ...

Melexis is aiming at electric motors with family of angle-sensing absolute magnetic encoder ICs that can work at high speed and typically deliver 1° accuracy or better. “By detecting the three ...
