If you’re not used to
mechanics and the like, then you might be wondering what a 12 volt DC motor is. Well, a 12 volt
DC motor is a simple kind of engine that uses two oppositely polarized magnetic energies in
order to create a torque, which is a force that causes the rotors to start rotating.
The whole process is
basically transforming electronic energy from the DC electricity into mechanical
Usually DC motors need
at least one electromagnet in order to work. The magnet alternates between the two poles in
order to keep the engine running. These motors don’t need a lot of electricity to work, and can
be used for a variety of things.
volt motor is used in simple machines like electric razors, remote controlled cars, as well as electronic car
windows. They are also great simple engines to tinker around with and to use for studying electromagnetism as
What is a DC motor? There is a more detailed
explanation on the next page, but here we'll highlight that there are different kinds of 12v DC
motors, which have different uses.
1.Brushed 12V DC
Brushed DC motors use stationary magnets and magnets that rotate. These are affordable and easy to find, and they
work very well too. They are high maintenance though, and also don’t last very long if used on high intensity. You
will need to replace the brushes and springs every so often, and clean the commutator.
2.Brushless 12VDC Motors
Brushless DC motors only require a
rotating magnet and some stationary electric magnets as well. This runs on DC and converts it to AC. These last
long and are very efficient, and you don’t even need to maintain them much. They are quite expensive though, and
are sometimes complicated to use.
are used in most computers because of their simplicity and low-maintenance, since there aren’t any brushes to
worry about. They are quite small, which is also useful.
DC Motor - Buying Considerations
plan to buy a 12 VDC motor, no matter what you plan to use it on, then make sure you’re sure of exactly what
kind you want to buy. You don’t want to buy something that you won’t end up using at all.
you’ve figured out what you want, then you should start your search online, rather than in your local electronics
store. This is because firstly, it’s a lot easier to sit and type in the search bar than getting up and going
Not to mention it
presents you with a lot of different 12 volt
motor options for you to choose from, rather than the limited variety you might
find in a store. And the chances of finding the perfect unit for your use are much
There are many
different online marketplaces for you to look through, and many of them probably service your
12 volt DC motors run from prices of three
hundred to five hundred dollars, and sometimes require shipping fees depending on where you
Despite the fees you
have to pay, shopping online is usually more fruitful then buying in a local store.
