Abstract
The utility model relates to a stator punching sheet of an aluminum welding electric machine of a washing machine. The stator punching sheet comprises long inverted trapezoidal grooves and short inverted trapezoidal grooves, wherein the long inverted trapezoidal grooves and the short inverted trapezoidal grooves are uniformly distributed alternately on the stator punching sheet, an opening of each inverted trapezoidal groove is slightly shrunk, the stator punching sheet is in a round-square shape, the inner diameter of the stator punching sheet is D1mm, the outer diameter of the stator punching sheet is D2mm, the side length of the square is L1mm, the depth of the short inverted trapezoidal groove is B1mm, the depth of the long inverted trapezoidal groove is B2mm, and the distance between the two inverted trapezoidal grooves is C, wherein D1 = phi 62-phi 70 mm, D2 = phi 115-phi 120 mm, L1 = 112-115 mm, B1 = 12.6-14.6 mm, B2 = 13.6-15.6 mm, and C = 3.7-4.6 mm. According to the stator punching sheet disclosed by the utility model, the efficiency of the aluminum welding electric machine can achieve or exceed the efficiency of a copper welding electric machine, and the manufacturing cost of the electric machine can also be greatly reduced.
Description
Technical field:
The utility model relates to a kind of stator punching, particularly relates to a kind of stator punching of washing machine electric machine with aluminium winding.
Background technology:
Be energy savings, national standard has proposed enforceable efficiency standard to washing machine and motor thereof, does not reach enforceable efficiency standard, and washing machine and motor thereof do not allow to sell.
Existing motor for washer generally adopts the copper cash motor, and the copper cash electric efficiency is higher, but cost is high, and profit is low, does not fit into low-cost requirement.For reducing cost; Present most manufacturer changes the copper cash motor into electric machine with aluminium winding, but generally still adopts the stator punching of copper cash motor, and the stator punching with the copper cash motor is used on the electric machine with aluminium winding like this; Also exist electric efficiency low, cost reduces unconspicuous problem.
Summary of the invention:
The purpose of the utility model is to provide the stator punching of a kind of low cost, washing machine electric machine with aluminium winding that efficient is high, to overcome weak point of the prior art.
The purpose of the utility model is achieved in that the stator punching of washing machine electric machine with aluminium winding, comprises long dovetail groove, the short dovetail groove that falls of falling, and on stator punching, falls the order of dovetail groove and evenly distributes by long two weak points of dovetail groove that fall; The opening of falling the dovetail groove shrinks slightly, and the stator punching profile is a square circular, it is characterized in that: stator punching inside diameter D 1mm, D outer diameter 2mm; Square length of side L1mm, the short groove depth of falling dovetail groove B1mm, the long groove depth of falling dovetail groove B2mm, two spacing C between the dovetail groove; Described D1=Φ 62～Φ 70mm, D2=Φ 115～Φ 120mm, L1=112～115mm; B1=12.6～14.6mm, B2=13.6～15.6mm, C=3.7～4.6mm.
The utility model is used in the washing machine electric machine with aluminium winding, not only can make the efficient of washing machine electric machine with aluminium winding meet or exceed the copper cash efficiency of motor, can also reduce the manufacturing cost of motor greatly.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is a utility model flute profile partial enlarged drawing.
1. the long dovetail groove that falls, the 2. short dovetail groove that falls, 3. inside diameter D 1,4. spacing C, 5. D outer diameter 2, and 6. square length of side L1 7. lacks the groove depth of falling dovetail groove B1,8. grows the groove depth of falling dovetail groove B2.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described further.
The stator punching of washing machine electric machine with aluminium winding comprises long dovetail groove 1, the short dovetail groove 2 that falls of falling, and on stator punching, falls the order of dovetail groove 2 and evenly distributes by long 1 two weak points of dovetail groove that fall, and the opening of falling the dovetail groove shrinks slightly; The stator punching profile is a square circular, it is characterized in that: stator punching inside diameter D 1mm3, D outer diameter 2mm5, square length of side L1mm6; The short groove depth of falling dovetail groove B1mm7, the long groove depth of falling dovetail groove B2mm8, two spacing C4 between the dovetail groove; Described D1=Φ 62～Φ 70mm, D2=Φ 115～Φ 120mm, L1=112～115mm; B1=12.6～14.6mm, B2=13.6～15.6mm, C=3.7～4.6mm.
