QUESTION re: Building a Simple Motor Experiment
Posted: Wed Nov 11, 2020 2:02 pm
While doing background research concerning the linked experiment below, I discovered that the three parts of a motor are the stator, the rotor, and the commutator. From what I gather, in this experiment, the permanent magnet is the stator and the temporary magnet, or electromagnet, is the rotor.
However, what I can't figure out is what plays the role of the commutator. From what I understand, the commutator reverses the magnet's polarity to make sure the axle continues to spin in one direction, so I'm assuming there must be one. Can you help me label the parts of the simple motor that function as the commutator?

PS I'm hoping I may have answered my own question after reading the procedure more thoroughly...
Would I be correct that, in this experiment, there is no commutator? That, by only stripping half of the wire on the right side, the insulation interrupts the current half of the time (keeping it from being repelled in the other direction), and that the force of the motion keeps it moving forward until it gets another push from the current?
Moderator Notes: Christi, I merged your two questions ... so the experts will see that no one has replied!
And a question: are these questions in regard to a student doing a hands-on science project? That's what the Ask the Expert forum is here for! Thanks!
