ABSTRACT:
An electric motor in which polarities of a stator and the number of polarities thereof are converted by converting the polarity of current depending on a rotation position of a rotor made of a permanent magnet so as to enhance attraction and repulsion occurring between the rotor and the stator, so that a rotative force of the rotor can be achieved with minimum power. The electric motor includes a stator having a plurality of iron cores fixably mounted within a main body at a predetermined distance and a plurality of coils wound in the plurality of iron cores, a rotor disposed in a center portion of the main body, having a permanent magnet having a predetermined number of polarities between an upper cover formed in an integral form with a connecting portion and a lower cover, a current converter screwed to the connecting portion of the rotor externally protruded over a cover of the main body, for supplying current to coils wound in the iron cores and converting polarity of current, a brush fixing portion for supplying main current to the current converter and fixing a plurality of brushes which supply current to the coils through the current converter, and a current supply portion mounted in the cover of the main body and connected to the plurality of brushes, for supplying current to the coils wound in the iron cores.
