Abstract
The invention discloses a stator iron core of motor used in the compressor of air-conditioner. The invention is formed by layered several iron core punching sheets which have several combination grooves with one concave surface and one project surface formed uniformly on the their periphery edges. The number of said combination groove is 4-8 in the shape of cube. The inventive stator iron core can utilizes the interactive matching between the combination grooves of each iron core punching sheet to assemble the stator iron core without welding. Therefore, the invention has simple assembling method, while it can reduce the manufacturing process, decrease the cost, cancel the welding device and avoid the pollution on the surface of stator iron core.
Description
Technical field
The present invention relates to a kind of air conditioner, particularly relate to a kind of stator core of motor for air conditioner compressor.
Background technology
Usually, air conditioner is a kind of device that makes its inner refrigerant carry out the kind of refrigeration cycle be made up of compression process, condensation process, expansion process and evaporation process.In air conditioner, the refrigerant that becomes high-temperature high-pressure state through overcompression can dispel the heat to the outside in condenser, and when flowing through expansion valve, significantly reducing its temperature and pressure, this low temperature, low pressure refrigerant can absorb heat when flowing through evaporator then, flow back to condenser at last again.Wherein, compression process, condensation process and expansion process are to carry out in the off-premises station of air conditioner, and evaporation process is then carried out under the effect of indoor unit blowing fan and heat exchanger.Fig. 1 is the business air conditioner electric moto used in compressor stator core structure end view of prior art.As shown in Figure 1, the stator core of this business air conditioner electric moto used in compressor is a plurality of laminations that are stamped to form 1 are stacked together and are symmetrically welded many places vertically and make on its circumference.Because this stator core need be welded when assembling, thereby not only can increase operational sequence, and owing to needing consumption scolding tin and investment weld mold that its manufacturing cost is raise.Also can pollute the surface of stator core when particularly adopting the method for welding to assemble.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide the stator core that a kind of assemble method is simple, production cost is low and can not pollute the motor for air conditioner compressor on its stator core surface.
In order to achieve the above object, the stator core of motor for air conditioner compressor provided by the invention is to be stacked together and to be formed by a plurality of iron-core laminations, and described iron-core lamination evenly is formed with recessed and the engagement groove that another side protrudes of a plurality of one sides along its neighboring.
Described engagement groove quantity is 4～8.
Described engagement groove is shaped as cube shaped.
The stator core of motor for air conditioner compressor provided by the invention is evenly to form recessed and the engagement groove that another side protrudes of a plurality of one sides on each iron-core lamination of stator core forming, utilize like this that being meshing with each other of engagement groove just can be assembled into stator core on each iron-core lamination, and need not to adopt the mode of welding, thereby not only assemble method is simple, and can reduce operation and reduce cost, and can not pollute the surface of stator core.
Description of drawings
Be elaborated below in conjunction with the stator core of the drawings and specific embodiments to motor for air conditioner compressor provided by the invention.
Fig. 1 is the business air conditioner electric moto used in compressor stator core structure end view of prior art.
Fig. 2 is a business air conditioner electric moto used in compressor stator core structure end view of the present invention.
Fig. 3 is a business air conditioner electric moto used in compressor stator core engagement groove of the present invention position engagement cutaway view.
Embodiment
As Fig. 2, shown in Figure 3, the stator core of motor for air conditioner compressor provided by the invention is to be stacked together and to be formed by a plurality of iron-core laminations 2, and described iron-core lamination 2 evenly is formed with recessed and the engagement groove 3 that another side protrudes of a plurality of one sides along its neighboring.Described engagement groove 3 quantity are 4～8, and it is shaped as cube shaped.When the assembling stator core, at first will form engagement groove 3 alignment on each iron-core lamination 2 of stator core, on the iron-core lamination 2 at two ends, pressurize then so that engagement groove 3 rear ends of previous iron-core lamination 2 are inserted in the engagement groove 3 of back one iron-core lamination 2, just can combine tightly between adjacent like this two iron-core laminations 2, utilize this closed assembly mode a plurality of iron-core laminations 2 can be fitted together, wait the connection operation thereby need not to adopt, so method of operation is simple and production cost is low such as welding.
Claims (3)
1, a kind of stator core of motor for air conditioner compressor, it is to be stacked together and to be formed by a plurality of iron-core laminations, it is characterized in that: described iron-core lamination (2) evenly is formed with recessed and the engagement groove (3) that another side protrudes of a plurality of one sides along its neighboring.
2, the stator core of motor for air conditioner compressor according to claim 1 is characterized in that: described engagement groove (3) quantity is 4～8.
3, the stator core of motor for air conditioner compressor according to claim 1 is characterized in that: described engagement groove (3) is shaped as cube shaped.
