12 Volt DC Motors

Electric Motors


Electric motors convert electrical energy to mechanical energy.  Generators like an alternator or a dynamo is what reverses the process by creating electrical energy from mechanical energy. 

By the same token, several types of electric motors are able to be run as a generator and vice versa.  For instance, a generator used for a gas turbine or a traction motor can be used on vehicles typically perform both tasks.

DC and AC electric motors are versatile because they can be found in household appliances, big industrial fans, pumps and blowers, power tools, machine tools and even disk drives.  Small electric motors are most often found in electric wristwatches.  AC electric motors suppliers of medium sized motors have the characteristics necessary for providing a convenient mechanical power for industrial uses. 

Large AC electric motors manufacturers create these motors for propulsion of ships, pipeline compressors, and most often water pumps with ratings in the millions of watts.  If you are interested in learning how electric motors work, it is important to know that electric motors are classified by the source of electric power, by their application, internal construction, or the kind of motion given.  Industrial electric motors work on the physical principle of production of mechanical force caused by the interactions of an electric current as well as a magnetic field from as early back as 1821.

Electic motors function after magnetic fields interact with conductors that carry current. With the help of a generator, the process may be reversed, that is, mechanical energy is changed over to electrical energy.  Alternating current motors are industrial electric motors that are sub-classified into other types such as  AC synchronous, AC induction shaded pole and AC induction split-phase capacitor. 

Of the three types, the AC induction will cost you less.  It has a long shelf life and high power capacities despite its lower price.  The main disadvantage of this type is the electric motors tendency to slip while rotating. 

Furthermore it has a low rotating force. The most common applications are found in fans.  With direct current motors or DC motors, they run with the help of a direct current, which is discussed in more detail on another section of this site.
