The first part of the tutorial looks inside of a Brushless DC Motor, or, BLDC. Then I show a discrete transistor circuit that can drive one. Of course, you’ll need a Microcontroller like an Arduino to drive it! Lastly, I briefly talk about an ESC.
Overall, a BLDC is better than a Brushed DC Motor (talked about those on #20) because:
- There are no brushes to wear out
- No sparks when the motor spins
- You can get way faster RPMs out of a BLDC.
