19/02/2016· The motor in our hair dryer had five loops, and so it was called a five-pole motor. So now we're going to see if we can use this motor to do some work. So we're going to take our washer here, and we're going to just mark out some circles in paper. And we'll take some scissors, and we're going to cut those circles out. I'm going to make a little tiny fan out of this paper. Now the motor …

DC Motors -- principles of operation

Every DC motor has six basic parts -- axle, rotor (a.k.a., armature), stator, commutator, field magnet(s), and brushes. In most common DC motors (and all that BEAMers will see), the external magnetic field is produced by high-strength permanent magnets 1. The stator is the stationary part of the motor -- this includes the motor casing, as well ...
