Technical field
The utility model relates to the stator laminating structure design of refrigeration compressor motor, specifically a kind of refrigeration compressor motor small-rabbet stator punching.
Background technology
Energy-saving electrical equipment progressively becomes the main flow household appliances in market, and air-conditioning, refrigerator etc. " large electricity consumer " become needs improved major products classification, the development trend in the market that faces the future, and industrial transformation becomes the huge challenge that enterprise faces.Meanwhile, during " 12 ", the situation of energy-saving and emission-reduction sternness is had higher requirement to refrigeration industry.
As, refrigerator has become the go to the countryside product of sales volume maximum in product of household electrical appliances, account for go to the countryside 50% left and right of all production marketing total amounts of household electrical appliances.Because the scope of application of refrigerator is wide, energy consumption is large, and its energy-saving design is had to great practical value.
Refrigeration compressor motor is the critical elements of air-conditioning, refrigerator etc., and the notch of existing motor stator punching is conventionally wider, and iron core vortex consume and the consume of stagnant magnetic are higher, and groove tooth magnetic flux density is higher, causes electric efficiency lower.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of refrigeration compressor motor small-rabbet stator punching simple in structure.
In order to solve the problems of the technologies described above, the utility model provides a kind of refrigeration compressor motor small-rabbet stator punching, comprises stator punching lamellar body, in stator punching lamellar body, is provided with rotor hole; Around rotor hole, in stator punching lamellar body, be provided with stator slot; On pillar between described any two connected stator slots, be provided with groove tooth, between described any two connected groove teeth, form notch, described notch and rotor hole are interconnected.
Improvement as to a kind of refrigeration compressor motor small-rabbet stator punching described in the utility model: the quantity of described stator slot is 24, described 24 stator slots are evenly distributed in stator punching lamellar body along rotor hole successively.
Further improvement as to a kind of refrigeration compressor motor small-rabbet stator punching described in the utility model: the gap of described notch is 1～1.5mm.
Further improvement as to a kind of refrigeration compressor motor small-rabbet stator punching described in the utility model: the wide of described groove tooth is 4～5mm.
Further improvement as to a kind of refrigeration compressor motor small-rabbet stator punching described in the utility model: be provided with fixing hole on described punching lamellar body.
Further improvement as to a kind of refrigeration compressor motor small-rabbet stator punching described in the utility model: described stator punching lamellar body adopts rectangular configuration; On the long limit of described arranged on left and right sides, be provided with three grades of steps.
Further improvement as to a kind of refrigeration compressor motor small-rabbet stator punching described in the utility model: the internal diameter of described punching lamellar body at 39mm between 49mm.
Refrigeration compressor motor small-rabbet stator punching of the present utility model has adopted rectangular setting, and this rectangular shape is more suitable for processing, and production cost is more low.And owing to being uniformly distributed 24 stator slots in stator punching lamellar body, by reducing the method for notch, broadening groove tooth, then reduced magnetic loss, thereby effectively raised the efficiency of motor.And in use procedure, the utility model has used the profile of rectangle, and added three grades of steps on the long limit, both sides of rectangle, by this set, made in the applicable motor of circular stator, electronics stator of the present utility model also can compatiblely use.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is the primary structure schematic diagram of refrigeration compressor motor small-rabbet stator punching of the present utility model;
Fig. 2 is the primary structure schematic diagram of stator punching of the prior art.
Embodiment
Embodiment 1, Fig. 1 have provided a kind of refrigeration compressor motor small-rabbet stator punching, comprise the stator punching lamellar body 4 of internal diameter between 39-49mm, in stator punching lamellar body 4, be provided with rotor hole 5(rotor hole 5 in stator punching lamellar body 4, the aperture of rotor hole 5 remains between 39-49mm); Around rotor hole 5, in stator punching lamellar body 4, be provided with 14 stator slots 1 of 24 stator slots 1, two and be evenly distributed in stator punching lamellar body 4 along rotor hole 5 successively; In 24 stator slots 1, between two stator slots 1 that are connected arbitrarily, all there is the interval of a pillar as two stator slots 1, in 24 stator slots 1, form 24 pillars, on pillar, be provided with groove tooth 3 arbitrarily, the wide of groove tooth 3 is 4～5mm, forms the notch 2 that width is 1～1.5mm between any two groove teeth 3, form 24 notches 2, and the gap of notch 2 is 1～1.5mm; By being interconnected between 14 stator slots 1 of 24 notches 2, two and rotor hole 5.
On punching lamellar body 4, be provided with fixing hole 6, by fixing hole 6, just can be easily by stacked some punching lamellar bodies 4 that need to combine together rear fixing; And stator punching lamellar body 4 adopts rectangular configuration, in manufacturing, compare circular configuration, the waste material of generation is more few, and operation is more simple, and cost also reduces accordingly; And on the long limit of the arranged on left and right sides of the punching lamellar body 4 of rectangular configuration, be provided with three grades of steps, because traditional stator punching is to have adopted circular structure mostly, so electric machine structure matching for more further compatible and circular stator punching, on the long limit of the utility model arranged on left and right sides, three grades of steps are set, form the slope that is similar to circular edges by three grades of steps, just can for, on some motors that match with circular configuration, use, also can on the motor of other structures, use compatible very strong.
Take the stator punching of internal diameter φ 44.6 as example:
Stator inner circle girth is: 44.6 × 3.14=140.04mm.
Stator punching lamellar body 4 has 24 stator slots 1, the arc length of each stator slot 1, and a corresponding groove tooth 3 and notch 2 sums are: 140.04/24=5.83mm.
If when notch 2 is respectively 1.8mm and 1.4mm, the length of corresponding groove tooth 3 is:
| Size/the mm of notch 2 | 1.8 | 1.4 |
| Size/the mm of groove tooth 3 | 4.03 | 4.43 |
Table 1
Can be drawn by above table 1, after the size of notch 2 changes 1.4mm into by 1.8mm, the wide of groove tooth 3 is increased to 4.43mm by 4.03mm, and the amount of increase is about 9%, therefore can reduce magnetic loss 9%, thereby improves electric efficiency.
Finally, it is also to be noted that, what more than enumerate is only a specific embodiment of the present utility model.Obviously, the utility model is not limited to above embodiment, can also have many distortion.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model, all should think protection range of the present utility model.
