How does An electic motor work?

Answer 1

To boil it down to simple terms, it is like holding two magnets together if the poles are different then it attacts, if they are the same then they repel.

That is basically how it works. You have the field magnet and the armature. They make two magnets and the poles keep shifting so the armature will spin trying to catch up to the rotating force.

There is a web site called "How things work" do a google search on it and see if you can find it. They can explain it better than I . good luck

Answer 2

It's based on the fact that magnetic fields produce physical force that can move things. If you have ever played with magnets you have seen this in action as you use one magnet to attract another magnet or force it to move without touching it, depending on how you line up their poles. All magnets have a negative pole and positive pole. Like poles repel each other and unlike poles attract each other. So in a motor electricity is used to create magnetic fields that oppose each other and cause something to move which happens to the rotor. There is wiring loops attached to the rotating shaft that has an opposing magnetic field to a magnetic field caused by wiring in the housing of the motor that cannot move. The repelling action of the opposing magnetic fields causes the rotor to turn. If something prevents the rotor from turning than big problems can arise including a possible fire from heat buildup.

Answer 3

If you take 2 magnets and try to put the like poles together they repel each other. A motor uses electro-magnets in a circular pattern. The pole end of the shaft changes the polarity as the motor rotates, to push the "center shaft magnets" away from the "outside casing magnets" in a constantly changing circular polarity change that forces the inside and outside magnets away from each other.
