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.
