Abstract
The utility model discloses a stator structure of a motor-driven compressor. The stator structure of the motor-driven compressor is characterized in that a motor stator core sleeves a motor spindle and then is installed in an inner ring of a housing. The shape of a cross section of the motor stator core is square-and-round and the shape of a cross section of the inner ring of the housing is round. By adopting the above structure, the stator structure of the motor-driven compressor has following advantages. First, the structural machinability of the motor spindle and the die-casting aluminum housing are improved under a premise of not influencing the performance of a motor. Second, the flow resistance is reduced and the compressor efficiency is improved. Third, the utilization rate of stator silicon sheet material is improved, thereby reducing the complete machine cost.
Description
Relate to the field
The utility model relates to the air conditioning for automobiles field, particularly a kind of motor compressor stator structure.
Background technology
Along with the raising of expanding economy and living standards of the people, automobile has got into huge numbers of families.Along with popularizing of automobile, air conditioning for automobiles is being familiar with by people gradually also.
In motor compressor; Refrigerant needs the variation of compression flow ability completion status and the transmission of energy; General all adopt machine shaft be processed into hollow as refrigerant runner or make uneven shape at the casing inner ring, dented part as refrigerant channel.All there is certain defective in these two kinds of structures, precedingly a kind ofly receive that the structural limitations axle is can not be too thick, cross section of fluid channel can't be big again, the refrigerant path is tortuous, flow resistance is big, and it is poor that axle is processed into hollow manufacturability, and axle construction intensity and rigidity are bad; The uneven inner-outer circular part structure of a kind of casing in back strengthens, and manufacturability is poor during the discontinuous metalworking of interior circle.
Solve the above problems, neither influence motor properties, the processability of product structure that can improve electric machine main shaft and die casting aluminium casing again is the problem that prior art need solve.
The utility model content
The utility model technical problem to be solved is, a kind of motor compressor stator structure is provided, and neither influences motor properties, can improve the processability of product structure of electric machine main shaft and die casting aluminium casing again.
For solving the problems of the technologies described above, the technical scheme of the utility model is that a kind of motor compressor stator structure is characterized in that: described stator structure is to be installed in the casing inner ring after motor stator core entangles machine shaft; The cross sectional shape of motor stator core is a square circular, and the cross section of casing inner ring is a circular cross-section.
The square limit of described motor stator core and the space of casing inner ring are refrigerant channel, confirm the size in space according to the compressor of different model.
Described motor stator core is to be overrided to form after the silicon steel sheet cold stamping of 0.35-0.5mm is shaped, and its flute profile is a peariform slot.
A kind of motor compressor stator structure, owing to adopt said structure, this stator structure has the following advantages:
1, under the prerequisite that does not influence motor properties, improves the processability of product structure of electric machine main shaft and die casting aluminium casing;
2, reduce flow resistance, raising compressor efficiency; 3, improve stator silicon steel material utilance, and then reduced the complete machine cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation;
Fig. 1 is the structural representation of a kind of motor compressor stator structure of the utility model;
Fig. 2 is the motor stator core sectional view of a kind of motor compressor stator structure of the utility model;
In Fig. 1-2,1, motor stator core; 2, machine shaft; 3, casing inner ring; 4, refrigerant channel.
Embodiment
As shown in Figure 1, the utility model is a motor stator core 1; Solid motor rotating shaft 2; Casing inner ring 3; The cross sectional shape of motor stator core 1 is a square circular, and the cross section of casing inner ring 3 is a circular cross-section.
The square limit of motor stator core 1 and the space of casing inner ring 3 are refrigerant channel 4, confirm the size in space according to the compressor of different model.Be overrided to form after the silicon steel sheet cold stamping shaping of motor stator core 1 for 0.35-0.5mm, its flute profile is a peariform slot.
As shown in Figure 2; The direction of arrow is the flow direction of refrigerant among the figure, and the utility model produces the runner that the compressor refrigerant flows with square circular cross section motor stator core 1 structure on motor compressor, thereby increases sectional area that refrigerant flows, improves flow passage route, reduces flow resistance; Neither influence motor properties; Can improve the processability of product structure of electric machine main shaft and die casting aluminium casing again, improve stator silicon steel material utilance, and then reduce the complete machine cost.
General motor stator core shape majority is circular or square, and the present invention is exactly that stator core silicon steel sheet profile is designed to square punching on the disk basis, and its flute profile still keeps disk to use peariform slot, just has an area of the sheet stator core.It is constant to press the motor stator core processing process; Open the silicon steel sheet cold-punching mold earlier; Be washed into stator punching to the silicon steel sheet billot; Require individual punching of loosing to laminate into stator core according to motor performance again, embed enamel covered wire then and become Motor Stator Assembly, pack into casing and rotor cooperate just becomes the motor compressor motor.
Become the square-round section shape to reserve the runner that refrigerant flows motor stator core 1 Cross section Design, substitute generally with machine shaft be processed into hollow as refrigerant runner or make uneven profile of tooth at the casing inner ring, dented part as refrigerant channel.
According to the difference of motor performance, but this structure stator punching Development and Production is used for serial motor compressor motor product, to meet the need of market.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as the various improvement of having adopted the utility model technical scheme to carry out; Or directly apply to other occasion without improvement, all within the protection range of the utility model.
