AI Technical Summary

Benefits of technology

This configuration results in a brushless motor that is thinner, lighter, and more efficient, addressing the limitations of prior art by optimizing the interaction between the rotor and stator, thereby enhancing performance and meeting modern fan requirements.

Problems solved by technology

The centrifugal blowers have thinner bladders with higher density and have higher cost and great noises.
However currently, the requirement of the fan is light, thin, short and small and has a larger capacity, while the prior art cannot achieve the object.

Abstract

A motor structure comprises a rotor having a driving portion and a magnetic element; the magnetic element being assembled to a lower end of the driving portion; and a stator including an electrode sheet, a coil, and a seat; the coil winding around a stator flame assembling the seat; a magnetic induction portion being protruded from the electrode sheet; and the electrode sheet being installed to the seat. The rotor is pivotally installed to the stator and the magnetic induction portion of the electrode sheet is arranged corresponding to the magnetic element so that after conduction, the coil is interacted with the magnetic element by using phase differences therebetween.

Description

FIELD OF THE INVENTION [0001] The present invention relates to motors, and in particular to the rotor and stator of a brushless motor structure, specifically the structures of the magnetic element and electrode sheet of a brushless motor is designed so that the brushless motor is thinner, lighter and have a higher operation efficiency. BACKGROUND OF THE INVENTION [0002] Currently, fans are classified into two types, axial fans, and centrifugal blower. The axial fans have lower cost with a larger volume. The centrifugal blowers have thinner bladders with higher density and have higher cost and great noises. [0003] There are two kinds of fans are used in power devices. One is brushless motor and the other is carbon brush motor. In the brushless motor, the coil is wound around the stator and the rotor is assembled with magnetic elements, which are contrary to the conventional carbon brush motor. Thereby for the burshless motor, the rectifier needs not to contact the carbon brush for co...
