- TL;DR Summary
- I watched two YouTube videos. The first one showed how a simple DC motor works and the need for a commutator. But in the second video which is DIY of a DC motor, commutator is not used. Can someone help if I am missing something important?
I am a mechanical engineer and my experience with electrical systems is almost nil.
The concept of a simple DC motor explained here was quite interesting, especially the need of a commutator part:
And then I checked this DIY simple DC motor here and was confused because there was no commutator used:
I am confused because with the armature rotating for every 180°, won't there be a change in polarity thereby not letting it to rotate continuously?
