Motors

Another kind of motor is the BLDC. Otherwise known as the Brushless DC Motor. Unlike the motors we talked about in #20, a BLDC has no commutation ring or brushes. This means no sparks, longer life, and very fast RPMs. Commutation is done electrically. In this video, we show the inside of a BLDC and show two ways to control one.

This Addohms Brushed DC Motor Tutorial goes into the third dimension! Using a variety of 3D models, we show you what makes a brushed DC motor, a brushed DC motor. Then, like usual, we break two simple ways to control them with a microcontroller like the Arduino. You can use a single BJT Transistor (remember those from #10?), build your own H-Bridge, or use a popular H-Bridge chip.
