The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of refrigerator compressor motor stator is provided, the stator winding of this motor stator uses that the enamelled wire path is short, few with line, volume and resistance is less, can effectively improve electric efficiency, reduces production costs.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of refrigerator compressor motor stator, comprise stator core and stator winding, the stator core inwall is the uniform winding wire slot that is shaped on axially, stator winding is made of last winding wire bag and following winding wire bag, last winding wire bag and following winding wire bag are communicated with by the winding connecting line that is inlaid in tape insulation layer in the winding wire slot, the winding connecting line is made of main winding connecting line and auxiliary winding connecting line, and last winding wire bag internal diameter is greater than the stator core internal diameter, and following winding wire bag internal diameter is less than the stator core internal diameter.
And described insulating barrier is a polyester film.
And, described down winding wire bag end is coaxial curve inwardly extend and down winding wire bag inner end diameter less than the stator core internal diameter.
And the coaxial outside sweep in described upward winding wire bag end extends and goes up winding wire bag internal diameter greater than the stator core internal diameter.
Advantage of the present utility model and beneficial effect are:
1, the last winding wire bag internal diameter of this refrigerator compressor motor stator is greater than the stator core internal diameter, following winding wire bag internal diameter is less than the stator core internal diameter, the following winding wire bag of this kind structure is compact more, under the situation that stator winding circle remains unchanged, has effectively reduced time winding wire bag occupation space.
2, winding connecting line and the iron core inwall in the winding wire slot of the stator core inwall of this refrigerator compressor motor stator separated by polyester film, can effectively prevent iron core scratch winding connecting line, and increases the electrical strength between winding connecting line and iron core.
The winding connecting line of 3 refrigerator compressor motor stators is made of main winding connecting line and auxiliary winding connecting line, main winding connecting line and auxiliary winding connecting line roll off the production line simultaneously, reduce the stator production process, and in follow-up line bag trimming, be easy to put in order out the line bag profile of expectation.
4, the following winding wire bag end of this refrigerator compressor motor stator coaxial curve inwardly extend and down winding wire bag inner end diameter less than the stator core internal diameter, dwindled the size of time winding wire bag end, under the situation that stator winding circle remains unchanged, reduced the consumption of enamelled wire, the state basic policy that meets national energy-saving and emission-reduction, and the resistance of stator winding reduces, and thermal losses is less, effectively improves efficiency of motor.
5, the utility model is simple in structure, design science is reasonable, the stator winding path short, the volume of, stator winding few with line and resistance is less, can effectively improve electric efficiency, reduce production costs, reduce the compressor volume, reduce the confined space that takies refrigerator.

Embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection range of the present utility model with this.
A kind of refrigerator compressor motor stator, comprise stator core 2 and stator winding, the stator core inwall is the uniform winding wire slot 4 that is shaped on axially, stator winding is made of last winding wire bag 1 and following winding wire bag 3, last winding wire bag is packed in the upper end of stator core, following winding wire bag is packed in the lower end of stator core, last winding wire bag and following winding wire bag are communicated with by the winding connecting line that is inlaid in the winding wire slot, the winding connecting line is made of main winding connecting line 6 and auxiliary winding connecting line 5, the coaxial parcel polyester film 7 of winding connecting line outer wall in the winding wire slot of stator core inwall, last winding wire bag internal diameter is greater than the stator core internal diameter, the described coaxial outside sweep in winding wire bag end that goes up extends, following winding wire bag internal diameter is less than the stator core internal diameter, and the better mode of present embodiment curves inwardly extension and following winding wire bag inner end diameter less than the stator core internal diameter for following winding wire bag end is coaxial.Above-mentioned last winding wire bag, following winding wire bag and winding connecting line all are to be made of enamelled wire.
The installation site of narration the utility model and compressor concerns below:
The utility model is installed rotor 9 and rotating shaft 10 and is packed into from the top down in the stator of present patent application in compressor housing 8, also comprise compressor casing 12, piston crank mechanism 11 and muffler 13 in the compressor housing, because so the last winding wire bag internal diameter of stator enters in the stator core greater than the stator core internal diameter easily, though following winding wire bag internal diameter is less than the stator core internal diameter, and the coaxial extension that curves inwardly in winding wire bag end down, because this installation method enters in the stator for rotor is installed from the top down, so can not produce any influence to installing.
For certain particular motor, under the situation that does not change umber of turn distribution and enamelled wire line footpath, can save enamelled wire about 5%, the copper loss of corresponding winding resistance and enamelled wire also reduces about 5%.
