I want to know what type of motor this is. It has brushes, 2 coils, 1 electromagnet, and 1 commutator of copper in the middle. I have a lot of doubts because I'm learning.
Is this a universal motor or an AC motor with brushes?
I have concluded that the brushes have 2 different polarities, which will create a magnetic field on the electromagnet, but how does it move? Does the magnetic field of the electromagnet collide with another magnet there?
Does it have a fixed magnet?
What is that yellow thing? Is it a capacitor?
If the same system, with the same coils, would experience a current of 220 volts instead of 110 volts, would it create more power? I mean, does more intensity of current creates a more intense magnetic field, and so, more power?
