Abstract
The utility model discloses an intelligent electronic fan. The intelligent electronic fan comprises a main body motor, an intelligent controller and fan blades, and is characterized in that the main body motor comprises a rotor and a stator, and the stator and the rotor are based on fractional-slot constructions; the stator is equipped with 12 fractional slots, and the rotor is equipped with 8 magnetic poles. According to the utility model, the main body motor based on the fractional-slot structures can generate the following effects that: 1, a higher harmonic potential generated by the magnetic field non-sinusoidal distribution of the magnetic poles can be weakened; 2, the amplitude of a tooth harmonic potential can be weakened effectively; 3, the pulsating amplitude of the flux of each magnetic pole caused by an air gap permeance variation, and the pulsating loss on the surfaces of the magnetic poles, can be reduced, so that the running efficiency and safety of the motor can be improved.
Description
Technical field
The utility model relates to a kind of smart electronics fan, the especially improvement of its main body motor.
Background technology
Traditional intelligence electronics fan, comprise main body motor, intelligent controller and fan blade, wherein the main body motor is brushless electric machine, and the rotor of motor and stator do not adopt the structure of fractional-slot, so magnetic pole and magnetic field can produce high order harmonic component, high order harmonic component causes the loss of electric machine to increase easily, efficient reduces, and temperature rise is increased, and may cause that also the inductance of transmission line and electric capacity produce resonance, produce overvoltage, and contiguous communication line is produced interference.
Summary of the invention
In view of the deficiencies in the prior art, technical problem to be solved in the utility model has provided a kind of smart electronics fan that can weaken the high order harmonic component electromotive force in the motor.
The utility model takes following technical scheme to finish:
A kind of smart electronics fan comprises main body motor, intelligent controller and fan blade, and described main body motor comprises stator and rotor, and described stator and rotor adopt the fractional-slot structure, and described stator has 12 branch grooves, has 8 magnetic poles on the described rotor.
In the utility model, adopt the main body motor of fractional-slot structure can produce following effect: 1, can weaken the high order harmonic component electromotive force that the magnetic pole and magnetic field non-sine distributes and produces; 2, can weaken the amplitude of slot ripples electromotive force effectively; 3, reduce to change because of air-gap permeance the pulsating amplitude of the every utmost point magnetic flux that causes, reduced the pulsation loss of magnetic pole surfaces.Thereby motor operational efficiency and fail safe all are improved.
Description of drawings
The utility model has following accompanying drawing:
The structure cross-sectional schematic of the main body motor during the smart electronics that Fig. 1 provides for the utility model is fanned;
Fig. 2 is the rotor magnetic pole distribution schematic diagram among Fig. 1;
Fig. 3 is the divided stator groove distribution schematic diagram among Fig. 1.
Embodiment
Accompanying drawing has been represented the technical solution of the utility model and embodiment, further describes each relevant details and operation principle thereof of embodiment below more by reference to the accompanying drawings.
As Fig. 1, Fig. 2, shown in Figure 3, a kind of smart electronics fan of the present utility model, comprise main body motor, intelligent controller and fan blade, described main body motor comprises stator 1 and rotor 2, described stator 1 and rotor 2 adopt the fractional-slot structure, described stator has 12 branch grooves 3, has 8 magnetic poles 4 on the described rotor.In the present embodiment, greatly 119 centimetres of the rotor sheet increasing diameters of rotor 2 are compared the rotor sheet of traditional 110 cm diameters, and the utility model rotor sheet can improve power of motor and moment of torsion, reduces the heating of motor, thereby promote motor performance.
