The Differences Between Brushed and Brushless DC Motors

Posted by Johann Tang on Jul 31, 2020 7:32:03 PM

I will never forget my first engineering project involving motors.  I built a small elevator for a science class back in elementary school.  Of course, it worked great during the testing phase, but it failed to perform when it counted.
