By the stator magnetic poles, rotors, brushes, shells and other components. The stator poles are made of permanent magnets (permanent magnets), such as ferrite, aluminum-nickel cobalt, ND-FE-B materials.
According to its structural form can be divided into cylindrical type and tile type and so on.
The rotor is generally made of silicon steel laminated, enameled wire around the rotor core between the two slots (three slots that have three windings), its joints are welded in the commutator of the metal sheet. The electric brush is a conductive part connecting the power supply and the rotor winding, and has two kinds of properties, conductive and abrasion. Permanent magnet motor brushes using a single metal sheet or metal graphite brush, electro-chemical graphite brush.
