Electromagnetic compatibility, a daunting subject for most, is sometimes treated as an afterthought by professional designers, and often completely overlooked by hobbyists.
Sadly, DC motors can be noisy beasts. Not just in terms of what you can hear, but also in that mysterious electromagnetic spectrum. Electromagnetic interference will manifest itself in distorted electrical signals, poor performance, and in sever cases, even system failure. All of a sudden it doesn’t sound like an afterthought huh?
Thankfully improving the EMC of your system can be fairly straight forward. Although there are entire textbooks devoted to fully understanding the subject, in our newest Application Bulletin we explain how to reduce motor EMI with a few simple techniques and just enough background knowledge for you to know what’s going on.
So do take a look if you're considering adding vibration alerting or haptics to your new design; 5 minutes of reading could save you a whole lot of time later!
