Special electric motors are those developed to suit specific purposes. There are various types of special motors that vary according to the purpose in which they are deployed. The electric motor is a machine that not very important role in the process where it is inserted.
For those who do not know the motor is used with the function to transform electrical energy into mechanical energy. To exemplify we will take as an example the lift, surely you use it often, and it uses the engine to run. The function of the engine is to convert the energy into mechanical receives subsequently able to run the application.
Industrial processes and household appliances are also very common because it uses the engines. Not always we realize that something we use very frequently uses this engine to run. It turns out it is much more common than most people realize, and so are increasingly frequent.
Despite having a low power, the electric motor of permanent magnet is used in the automotive and toys
Is in operation five types of electric DC motors which are: permanent magnet motor AOM3458, the field engine series, parallel field motor (shunt), excitation motor independent motor and composite (compound).
The permanent magnet electric motor has a fixed magnet on the stator and the rotor which is wound the feed occurs with the help of a direct current power that leads with the aid of a brush-commutator assembly.
The power of the electric motor of permanent magnet is low, but despite this, the electric motor of permanent magnet is widely used in the automotive industry, in the toy industry and in various other industrial applications. The speed variation and simple voltage variation are the hallmarks of electric motor of permanent magnet. The permanent magnet electric motor can be used as an inexpensive tachometer.
