How does an Electric Motor work? (DC Motor)
Jared Owen
This video is sponsored by Brilliant. We'll cover the basics of electricity
and magnets and then put it all together to understand how the motor
works. The magnets do n't have to be in this shape, for example , some
magnets might be more flat like this. We 'll come back to it in a moment
to explain the concept of the spinning magnet. The electromagnet is
special in the sense that it can be turned on or off. It can do the same
things that a permanent magnet can. It has a north and a south pole,
which will attract or repel other magnets. Instead of flipping the battery,
an easier way to do this is to switch the wires. We need to add something
to the armature called a commutator. It 's a ring with gaps in the
opposite sides. The electromagnet switches polarity, which will cause
armature to keep spinning. Electromagnets are stronger when there are
more wires. Stronger torque means a faster spin.
What I 've shown you in this video is called a DC motor. If you have a
device that moves and is powered by a battery, there 's a good chance'
there will be an electric motor in it. The motor will have stronger
electromagnets, which means it will spin faster. The spinning of the
motor can be converted to other types of movement, such as the side-to-
side motion we see in this fan. The first 200 people will also get 20 % off
