Description
Technical field:
The utility model relates to a kind of motor stator core punching structure.
Background technology:
Present conventional motors stator core stamping chip architecture is provided with the punching of centre bore in the middle of comprising, in the inboard upper edge of punching 24 or 36 round bottomed vessels are set evenly circumferentially, and round bottomed vessel communicates with centre bore, in the cylindrical upper edge in the punching outside 4 side cuts is set evenly circumferentially.The parameters of traditional punching all can not adapt to: the requirement of low-cost high-efficiency mainly shows: 1) winding that need inlay of traditional core stamping is more, and amount of copper consuming is big, and cost is higher; 2) under the equal conditions, efficient is low, and staring torque is little.
Summary of the invention:
The purpose of this utility model provides motor stator core punching structure, its excellent performance, and the winding of inlaying is less, and amount of copper consuming is little, and cost is on the low side.
The purpose of this utility model is achieved by following technical proposals.
A kind of motor stator core punching structure is provided with the punching of centre bore in the middle of comprising, in the inboard upper edge of punching round bottomed vessel is set evenly circumferentially, and round bottomed vessel communicates with centre bore, round bottomed vessel area S scope: 34 square millimeters to 80 square millimeters scope; The scope of facewidth L scope: 3.3mm to 6.1mm; Center-hole diameter D scope is between 73mm to 75mm; Line embedding groove be uniformly distributed along the circumference and the bottom and one the circle tangent, between the diameter D of tangent diameter of a circle D1 and centre bore, satisfy the scope of following condition: D+18mm＜D1＜D+30mm; Line embedding groove quantity is 20 to 36 scope, and the diameter D2 of cylindrical is in 110mm to 120mm scope.
Above-mentioned described cylindrical upper edge in the punching outside circumferentially evenly is provided with 4 side cuts, and the scope of relative two side cut distance D 3 is in the scope of 107mm to 112mm.
The radius R of above-mentioned described round bottomed vessel is in 3.4mm to 6.7mm scope, height H 1 is in 6mm to 6.5mm scope, the width L1 of notch is at 1.9mm to 2.2mm, the height of groove shoulder H2 is in 1mm to 1.5mm scope, groove shoulder breadth degree L2 is in 4.5mm to 6mm scope, and center-hole diameter D is between 73.5mm to 74.5mm, and the diameter D2 of cylindrical is in 111mm to 113mm scope, the number of round bottomed vessel is the scopes of 24, two scopes of cutting edge at 107mm to 109mm.
The utility model compared with prior art has following effect: 1) contrast by experiment, punching of the present utility model (being called for short new punching) and traditional stator core stamping sheet (being called for short old punching) are done the parameters contrast,
By above contrast, under the equal conditions, new punching efficient of the present utility model is more increased, and staring torque more strengthens; 2) under the prerequisite of satisfied even the every performance of superior old punching, it is less that winding is inlayed in new punching of the present utility model, and consumption copper is lower, and the contrast cost can be saved motor copper 10% to 20%.
