DC motors are used in a variety of devices and have a very complex internal structure. This time, we disassembled a DC motor from a Mini 4WD and explained the motor's structure and the principles of rotation. In order to gain a deeper understanding of the roles of brushes and commutators, we actually built a primitive DC motor using paperclips, coils, magnets, etc. We also mentioned that in order to increase the rotational force, it is necessary to increase the strength of the current, and we verified this by creating sparks.
