Fan blade and rotor integrated brushless direct current motor

Abstract

The invention provides a fan blade and rotor integrated brushless direct current motor, and belongs to the field of brushless direct current motors. The fan blade and rotor integrated brushless directcurrent motor comprises a rotor and a stator which are coaxially arranged and relatively rotate, wherein the stator comprises a plurality of stator coils and two annular frames, the two annular frames are symmetrically arranged and serve as a fan shell to position the rotor arranged in the middle after being fixedly locked, the stator coils are evenly distributed and embedded in the sides, closeto the rotor, of the annular frames, and permanent magnets corresponding to the coil are arranged in the rotor. According to the invention, the fan blades and the motor rotor are combined into a whole, the functional part of the motor rotor is arranged on the outer ring of the rotor, the fan blades are arranged on the inner ring of the motor, and through the design of the fan blades with the variable inclination angle and the variable attack angle, the functions of higher efficiency, suitability for heat dissipation, forced air supply and the like in various electronic or mechanical equipmentare achieved.

Description

technical field [0001] The invention belongs to the field of brushless DC motors, and relates to a brushless motor, a coreless motor, a motor with a ring structure, and a fan blade rotor integrally formed motor, in particular to a fan blade rotor integrated brushless DC motor. Background technique [0002] For a long time, the study of the structure and evolution of the earth's interior has been an academic problem, and the research in this field will greatly affect all aspects of mineral exploration, earthquake prediction and engineering construction that are closely related to people's work and life. The scientific research community has been conducting artificial exploration and theoretical research on the geological structure, and the research results need to be verified by experiments, but the change of the geological structure is a very slow process. Therefore, it is necessary to simulate the tectonic deformation process on a large temporal and spatial scale through ex...
