Abstract
The utility model discloses a motor stator core punching. The motor stator core punching comprises a punching body provided with a centre hole at the center thereof; a plurality of round bottom grooves are circumferentially arranged at the inner side of the punching body and are communicated with the centre hole; the distance A between two opposite outer sides of the punching body is in a range of 114 to 124 mm; the diameter B of the centre hole is in a range of 51 to 58 mm; a tooth width C is in a range of 3.0 to 3.7 mm, a notch width D is in a range of 2.0 to 2.6 mm; the round bottom grooves are uniformly distributed along circumference, the bottoms of the round bottom grooves are tangent to a circle, and the diameter E of the tangent circle is in a range of 88 to 98 mm. The motor stator core punching has improved manufacturability, guarantees balance of a magnetic circuit and a moderate magnetic flux density and reduces noise and temperature rise of a motor.
Description
Technical field:
The utility model relates to a kind of motor stator core stamping sheet.
Background technology:
Traditional motor stator winding adopts the copper enamelled wire usually, copper enamelled wire proportion is 3 times of aluminium enamel-covered wire, and expensive one times of cost ratio aluminium enamel-covered wire has sizable cost advantage therefore the copper enamelled wire is used aluminium enamel-covered wire instead, now generally adopts the copper cash punching, conceptual design motor with the iron core thickening, but than large many of copper, aluminium enamel-covered wire motor mass production processes is poor because of the resistivity of aluminium, and magnetic circuit is uneven, the shortcomings such as iron core is thicker, and motor noise is large highlight.
Summary of the invention:
The purpose of this utility model is to provide a kind of good manufacturability, magnetic circuit balance, motor stator core stamping sheet that magnetic flux density is moderate.
The purpose of this utility model is achieved by following technical proposals.
A kind of motor stator core stamping sheet, the punching body of centre bore is set in the middle of comprising, on punching body inboard, some round bottomed vessels are set circumferentially, round bottomed vessel communicates with centre bore, the scope of two relative outer side edges distance A of punching body is between 114mm to 124mm, the diameter B scope of centre bore is 51mm to 58mm, facewidth degree C is between 3.0mm to 3.7mm, the scope of slot opening D is between 2.0mm to 2.6mm, round bottomed vessel be uniformly distributed along the circumference and the bottom and one the circle tangent, the scope of tangent diameter of a circle E is between 88mm to 98mm.
Punching body described above is square, and the outer side edges of punching body is by the arc-shaped side transition.
The quantity of some round bottomed vessels described above is 24.
The round bottomed vessel outside, punching body described above are provided with through hole.
the utility model compared with prior art, have following effect: 1) scope of two relative outer side edges distance A of the punching body of the utility model stator core stamping sheet is between 114mm to 124mm, the diameter B scope of centre bore is 51mm to 58mm, facewidth degree C is between 3.0mm to 3.7mm, the scope of slot opening D is between 2.0mm to 2.6mm, round bottomed vessel is uniformly distributed along the circumference and bottom and is justified tangent, the scope of tangent diameter of a circle E is between 88mm to 98mm, larger stator outer diameter and less diameter of stator bore, mix the suitable stator facewidth, for electric machine with aluminium winding design provides punching platform preferably, vat has improved manufacturability, the enough large facewidth and yoke section, guaranteed the magnetic circuit balance, magnetic flux density is moderate, reduced motor noise, reduced electric machine temperature rise, 2) under the prerequisite that satisfies even superior traditional punching properties, aluminium enamel-covered wire is used in punching of the present utility model, reduces costs, and strengthens product in the competitiveness in market.
