Abstract
The utility model discloses a kind of novel small-sized wind power generator rotors, are mainly made of slotted vane, permanent magnet, positioning screw, nut.Slotted vane is made of silicon steel sheet, has 10 dovetail grooves in the radially equidistant punching of its circumference, equidistant punching has 4 location holes in the middle.Permanent magnet section be it is arc-shaped, two sides are machined with oblique angle.4 positioning screws respectively penetrate 4 positioning holes of slotted vane, and one end is secured with nuts.This wind power generator rotor have the advantages that structure it is simple, it is easy for installation, run smoothly reliable, be suitble to apply in the various small-sized wind power generators of 100~1000W.
Description
Technical field
The utility model relates to wind power generator rotors, refer in particular to a kind of small-sized wind power generator rotor.
Background technique
With the development of the social economy, the farming and pastoral area vast in China has occurred by a few family peasants and herdsmen, several wind-power electricity generations
Unit is unified into the off-grid minor scale power net in part, and power mode is also from illuminating, see TV or gradually develop from electricity is picked up between battery
It is larger to electricity consumptions such as electricity consumption pumping water, Dairy Processings and directly take electricity from electric control system and indirectly take electricity from battery
Parallel production method, thus to the rotational speed regulation of wind power generating set, the performance of power regulation and job stability, reliable
Property proposes higher more accurate requirement.
Currently, the generator amature matched with small wind turbine of China's production still follows conventional electric power generation motor rotor structure,
That is rotor surrounding is machined with rectangular channel, and permanent magnet section is also rectangle, and when installation, permanent magnet is embedded in the rectangular channel of slotted vane
It is interior, then use adhesive bond.Since northern China is dry, binder is easy to lose adhesive effect, when rotor is in high speed
When rotary work, under the influence of centrifugal force, permanent magnet is easy to will appear the failure for loosening or falling off, and largely effects on wind-power electricity generation
Stability, the reliability of machine when serious, will cause generator and scrap because of short-circuit scaling loss.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of novel small-sized wind power generator rotor, this wind-force hair
Motor rotor construction is simple, light-weight, and when work, permanent magnet can be fixedly secured in dovetail groove for a long time, not easily to fall off, it is ensured that wind
Power generator job stability, reliability, and it is unified for wind-driven generator product quality, realize seriation, standardization and specification
Metaplasia produces offer condition.Significantly improve wind-driven generator working efficiency.
The technical problems to be solved in the utility model with flowering structure by being realized: a kind of novel small-sized wind-driven generator turns
Son is mainly made of slotted vane, permanent magnet, positioning screw, nut, and the slotted vane is made of silicon steel sheet, radially equidistant in its circumference
Punching has 10 dovetail grooves, and the bevel angle α of two sides is 6 °~8 ° in dovetail groove, and dovetail groove depth L is 2.0mm~3.0mm.
The permanent magnet section be it is arc-shaped, two sides are machined with oblique angle, and angle δ is 6 °~8 °.When installation, by permanent magnetism
The oblique angle of iron two sides is embedded in the dovetail groove of slotted vane, is then bonded with binder.
Equidistantly punching has 4 location holes in the middle part of slotted vane.4 positioning screws respectively penetrate 4 positioning of the slotted vane
In hole, one end is secured with nuts.When in order to guarantee working rotor, slotted vane is not along the outside vibration of positioning screw, in positioning screw two
Nut and positioning screw end are welded by end with electric welding with slotted vane.The rotor is mounted in generator unit stator by axis and bearing
Between.
This small-sized wind power generator rotor advantage is: 1. structures are simple, install easy to make；2. light-weight, operation is flat
Surely reliably, when work, permanent magnet can be securely fixed in dovetail groove for a long time, be suitble to China, Arid Area, the north to use, be not easy
It loosens and falls off；3. its geometry can meet design performance requirement；4. being suitable in the various small winds of 100W~1000W
It is applied in generator.

Specific embodiment
In order to illustrate more clearly of technical solutions of the utility model, one is done with reference to the accompanying drawing and is elaborated, so that this reality
It is easier to be readily appreciated by one skilled in the art with novel advantage and feature, to make more the protection scope of the utility model
Explicitly define.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, this generator amature, mainly by slotted vane 5, permanent magnet 6, positioning screw 7, nut
8 compositions；
The rotor 1 is mounted among generator unit stator 2 by axis 3 and bearing 4.
As shown in figure 5, the slotted vane 5 is made of silicon steel sheet, there are 10 dovetail grooves in the radially equidistant punching of its circumference, at it
The radially equidistant punching in middle part has 4 location holes, and one of location hole is machined with locating slot；10 dovetail groove depth L are 2.5mm,
Its internal two sides and radial direction included angle α are 7 °；
As shown in fig. 6,6 section of permanent magnet be it is arc-shaped, two sides are machined with oblique angle, and angle δ is 7 °；
As shown in Fig. 2, 4 positioning screws 7 respectively penetrate 4 positioning holes of slotted vane 5, the other end is solid with nut 8
Fixed, slotted vane 5 by nut 8 and will not be determined along the outside vibration of positioning screw 7 at 7 both ends of positioning screw when in order to guarantee that rotor 1 works
Position 7 end of screw rod is welded with slotted vane 5.
