BRUSH MOTOR

The present invention relates to a brush motor. The purpose of the present invention is to provide a brush motor wherein the same is structured to have four poles, twenty-four slots, and two brushes; the pole arc/pole angle ratio, which is the ratio of the magnet width against the pole interval, is optimized, thereby enabling compactness and lightness; and generation of "cogging torque" and "ripple current", which result from a change in the magnetic field between a rotor and stators, is minimized, thereby improving the rotation performance of the motor. In order to accomplish the above purpose, the present invention provides a brush motor comprising: a motor housing; a plurality of stators installed on the inner peripheral surface of the motor housing at an interval; a rotor rotatably installed inside the stators; a plurality of commutators installed at the rotation center axis of the rotor; and a plurality of brushes for applying electricity to respective commutators, wherein the rotor comprises multiple slots formed on the outer peripheral surface thereof at an interval and a plurality of coils wound around respective slots. Four stators are installed on the inner peripheral surface of the motor housing. Two brushes apply electricity to respective commutators of the rotor. Twenty-four slots of the rotor undergo drawing and repelling actions with the four stators, respectively, and generate rotational torque when excited or demagnetized by applied current, and twenty-four coil parts are wound around the slots, respectively, thereby providing a structure comprising four poles, twenty-four slots, and two brushes. La présente invention concerne un moteur à balais. L'objet de la présente invention est de fournir un moteur à balais qui est structuré pour avoir quatre pôles, vingt-quatre fentes et deux balais ; le rapport arc polaire/angle polaire, qui est le rapport de la largeur d'aimant à l'intervalle polaire, est optimisé, ce qui permet une compacité et une légèreté ; et la génération d'un « couple de détente » et d'un « courant ondulatoire », qui résultent d'un changement du champ magnétique entre un rotor et des stators, est réduite au minimum, ce qui permet d'améliorer les performances de rotation du moteur. Afin d'atteindre l'objectif ci-dessus, la présente invention concerne un moteur à balais comprenant : un carter de moteur ; une pluralité de stators installés sur la surface périphérique interne du carter de moteur à un intervalle ; un rotor install
