Abstract
The utility model relates to a wind generator rotor, comprising a stator body, wherein the stator body is formed by a plurality of silicon steel plates (1) through continuous lamination, and the silicon steel plates (1) are provided with an annular structure with a center hole (2). The wind generator rotor is characterized in that the annular areas of the silicon steel plates (1) are respectively provided with four sector grooves (3) and the annular areas between adjacent sector grooves (3) are respectively provided with a mounting hole (4). The annular areas of the silicon steel plates are respectively provided with four sector grooves, thereby reducing the weight of the wind generator rotor, and being high in energy conversion efficiency.
Description
Technical field
The utility model relates to a kind of wind power generator rotor, belongs to the mechanical & electrical technology field.
Background technology
Wind-driven generator by head, turn, empennage, blade form.Each part is all very important, and the each several part function is: blade is used for accepting wind-force and transfers electric energy to through head; Thereby empennage makes blade obtain maximum wind energy facing to the direction of the wind comes from all the time; Turn head is rotated to realize the function of empennage adjustment direction neatly; The rotor of head is a permanent magnet, and the stator winding cutting magnetic line produces electric energy.Traditional wind power generator rotor forms through stacked the pressing solidly of multi-disc solid silicon steel disc, because rotor not stall when work is moving, solid silicon steel sheet rotor is too heavy, and energy conversion efficiency is lower.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of energy conversion efficiency higher wind power generator rotor.
The purpose of the utility model is achieved in that
A kind of wind power generator rotor; Comprise stator body; Said stator body is formed by continuous stacked the pressing solidly of multi-disc silicon steel sheet; Said silicon steel sheet is the loop configuration that has centre bore, evenly is provided with 4 fan grooves on the annular region of said silicon steel sheet, and the annular region between the said adjacent fan groove is equipped with an installing hole.
Compared with prior art, the beneficial effect of the utility model is:
Evenly be provided with 4 fan grooves on the annular region of the utility model silicon steel sheet, make that the weight of this wind power generator rotor is alleviated, energy conversion efficiency is higher.
Description of drawings
Fig. 1 is the utility model wind power generator rotor structural representation.
Wherein:
Silicon steel sheet 1
Centre bore 2
Installing hole 4.
Embodiment
Referring to Fig. 1; A kind of wind power generator rotor that the utility model relates to comprises stator body, and said stator body is formed by multi-disc silicon steel sheet 1 continuous stacked pressing solidly; Said silicon steel sheet 1 is for having the loop configuration of centre bore 2; Evenly be provided with 4 fan grooves 3 on the annular region of said silicon steel sheet 1, the central angle of said fan groove 3 points to the center of circle of centre bore 2, and the annular region between the said adjacent fan groove 3 is equipped with an installing hole 4.
Claims (1)
1. wind power generator rotor; Comprise stator body; Said stator body is formed by continuous stacked the pressing solidly of multi-disc silicon steel sheet (1); Said silicon steel sheet (1) is for having the loop configuration of centre bore (2), it is characterized in that evenly being provided with 4 fan grooves (3) on the annular region of said silicon steel sheet (1), and the annular region between the said adjacent fan groove (3) is equipped with an installing hole (4).
