Abstract
The utility model provides a wind driven generator stator and a wind driven generator. The wind driven generator stator comprises a yoke portion, tooth portions, round bottom grooves and positioning grooves, wherein the tooth portions used for enhancing magnetic conduction are arranged on the yoke portion; the round bottom grooves are arranged between adjacent tooth portions, and used for storing coils wound on the tooth portions and changing the winding direction of the coils; and the positioning grooves are arranged on the excircle of the stator and used for fixing the position of the wind driven generator stator. The wind driven generator stator provided by the utility model reduces copper loss and heat productivity through arranging the round bottom grooves. In addition, the wind driven generator stator enables the generator to generate larger current under the condition of a lower rotating speed through matching the 33 grooves with a rotor provided with 10 permanent magnets, and the starting resisting moment is reduced.

Along with the appearance of energy crisis and the people requirement to environmental protection, many countries, mechanism and personnel have given increasing attention to the new energy.Wherein, wind-force is widely used as a kind of energy of cleaning.Existing aerogenerator stator notch belongs to middle apart from winding, can't reach wind-driven generator and produce large electric current in slow-revving situation, the effect of low resistance of start square.
The utility model content
The utility model proposes a kind of aerogenerator stator and wind-driven generator, solved and to reach wind-driven generator in the prior art and in slow-revving situation, produce large electric current, the problem of low resistance of start square.
The technical solution of the utility model is achieved in that
A kind of aerogenerator stator comprises:
Yoke section is provided with in the described yoke section for the tooth section that strengthens magnetic conductance;
Be arranged between the adjacent described tooth section, be used for depositing the round bottomed vessel that is wrapped in the coil in the described tooth section and changes the coil-winding direction;
Be arranged at described stator cylindrical, be used for the fixedly location notch of aerogenerator stator position.
Further, also comprise: be arranged on described tooth section one end, be used for improving the crown of air-gap induction.The quantity of described round bottomed vessel is specially 33, and the quantity of described tooth section is specially 33.Aerogenerator stator is made by silicon steel sheet.
A kind of wind-driven generator comprises: casing, rotor, it is characterized in that,
Also comprise described aerogenerator stator, it is inner that described stator is installed in described casing; Described rotor is installed in described stator interior.
Further, described rotor is specially the rotor that 10 blocks of permanent magnets are housed.
Technical solutions of the utility model are by arranging described round bottomed vessel and tooth section, the reasonable coordination of yoke section, copper loss and iron loss have been reduced, in addition, by adopting 33 grooves to cooperate the described rotor that 10 blocks of permanent magnets are housed, and the employing fractional slot winding, thereby make generator in more slow-revving situation, can produce larger electric current, reduced resistance of start square.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
