What happens here
Patrick explains that 'brushless' is not just about the absence of brushes but implies a 'digital motor' with increased efficiency. He opens up a drill to illustrate the internal workings of a brushless motor, demonstrating how coils are alternately energized (akin to 3-phase power) to create rotation without physical contact. He contrasts this with brushed motors where sparking indicates friction and wear.
Goal: Patrick provides a detailed explanation of what a brushless motor is, contrasting it with traditional brushed motors and clarifying common misconceptions.
