Questions concerning about brushless dc motor

Click For Summary
SUMMARY

This discussion centers on the operation of brushless DC motors, specifically addressing the behavior of magnetic fields and components within the motor. Users inquire about the interaction between magnets and the rotor, questioning why magnets repel instead of attract in certain configurations. The conversation highlights the importance of understanding the magnetic properties of materials used, such as the cork and iron nail, and the role of magnetic wire in the circuit. The consensus suggests that visual aids, like instructional videos, can effectively clarify these concepts.

questions concerning about the brushless dc motor

in a brushless dc motor,does the power given by a battery move in and out throughout the electric current of the magnetic wire?

I have the magnetic wires both parallel to each other and placed at the negative and positive terminal of the battery. both magnetic wire are placed around an iron nail and it's situated on a beam so it's balance. in front of the iron nail is a cork with 2 magnets attached to it. i have also placed a needle through the cork so that the needle would fit in a little hole that can hold the cork and the 2 magnets attached to it. when i turn on the machine, the armature or cork starts spinning because the magnets are repelling. why do the magnets repel instead of attract in this particular situation?

What is a rotating rotor made out of and how does it push or pull when being used in a motor?

How does a cork with 2 magnets attach to it repel a magnetized iron nail magnetically in a brushless dc motor?

Do magnets in motor tend to repel or attract?
also how do magnets effect how the motor functions? and if stronger magnets would have a greater effect on the cork( we used a cork from a wine bottle and connected it with 1 magnets to the left and right side)

First, a wire is a wire. Magnetic wire is not a term.

Next, I think many of your questions are better answered with a video. Try this one.
