Stator 3 is made up of stator core 6, stator winding 7, and stator core 6 is major parts of main magnetic circuit, is formed by stator lasmination 8 closed assemblies, and it is the silicon steel sheet of 0.5mm that stator lasmination 8 adopts thickness.In stator lasmination 8, be formed with identical big wire casing of a plurality of shapes 9 and little wire casing 10, as embedding stator winding.
But in the single-phase induction motor used for compressor stator core construction of prior art, the number of the wire casing in stator lasmination is less; Though what have has a more wire casing in stator lasmination, and reasonable inadequately aspect the selection of diameter of stator bore and external diameter ratio.Make that the prior motor performance is not high, the complete machine fee of material is higher, cost rises, lacking of market competition ability.
Summary of the invention
The present invention proposes for the shortcoming that overcomes the prior art existence, and its objective is provides a kind of stator structure of single-phase induction motor used for compressor.
Technical scheme of the present invention is: a kind of stator structure of single-phase induction motor used for compressor, comprise stator core and stator winding, and stator core is formed by a plurality of stator lasmination closed assemblies.On the inner peripheral surface near stator lasmination, be uniformly distributed with four of 20 of big wire casings of formation and little wire casings, the inside diameter D 2 of described stator lasmination with the ratio of D outer diameter 1 is: 0.507≤D2/D1≤0.523; Stator sulculus footpath d with the ratio of stator vat footpath D is: 0.928≤d/D≤0.975; Stator slot spacing L is: 2.6mm≤L≤3.9mm; Angle r is between groove: 12.86 °≤r≤18 °; Angle i between groove between center line and the tongue and groove is: 45 °≤i≤54 °.
The inside diameter D 2 of stator lasmination with the optimum value of the ratio of D outer diameter 1 is: D2/D1=0.515; Stator sulculus footpath d with the optimum value of the ratio of stator vat footpath D is: d/D=0.967; The optimum value of stator slot spacing L is: L=3.0mm; The optimum value of angle r is r=15 ° between groove, and the optimum value of the angle i between groove between center line and the tongue and groove is: i=45 °.
The present invention compared with prior art, has saved the copper cash consumption because parameters such as stator core internal diameter, grooved, groove number have been carried out optimal design, and fee of material has reduced 2～5% under the identical performance condition of motor satisfying, and has improved the overall performance of motor.
