CN201163730Y - Stator punching sheet of industrial sewing machine enamel-cover aluminum wire motor - Google Patents

Abstract

The utility model provides a stator punching sheet for an enameled aluminum wire motor of an industrial sewing machine. The motor stator punching sheet is evenly distributed with a plurality of U-shaped wire grooves, the arc diameter of the top of the U-shaped wire groove is g=5.8-7.2mm, the narrowest part of the bottom is h=3.5-4.8mm, the opening width is j=2-2.3mm, and the caliber depth is i=1.5mm. The stator punching sheet has an outer diameter d=139±10mm, an inner diameter e=80±5mm, an outer diameter wide side a=134±10mm, b=130±8mm, c=34±5mm, and a wire groove top diagonal distance f=114±8mm. The utility model has the advantages that it can not only make the efficiency of the aluminum wire motor reach or exceed the efficiency of the copper wire motor, but also achieve the efficiency of the same motor output power, and can also greatly reduce the manufacturing cost of the motor.

Description

Stator laminations for enamelled aluminum wire motors for industrial sewing machines

technical field

The utility model relates to a motor for an industrial sewing machine, in particular to a stator punch made of aluminum wire wound by the motor.

Background technique

At present, the winding groove structure of the stator of the motor used in industrial sewing machines is mostly suitable for winding the stator coil with enamelled copper wire, and the cost is high. There is no motor stator punching sheet suitable for winding enamelled aluminum wire.

Contents of the invention

The purpose of this utility model is to provide a stator punch of an industrial sewing machine enamelled aluminum wire motor; the motor stator punch is evenly distributed with several U-shaped slots, and the arc diameter at the top of the U-shaped slot is g=5.8-7.2mm, The narrowest part of the bottom h=3.5-4.8mm, the opening width j=2-2.3mm, and the aperture depth i=1.5mm.

The stator punching sheet has outer diameter d=139±10mm, inner diameter e=80±5mm, outer diameter wide side a=134±10mm, b=130±8mm, c=34±5mm, and the diagonal line at the top of the slot Practice from f = 114 ± 8mm.

The utility model has the advantages that not only the efficiency of the aluminum wire motor can reach or exceed that of the copper wire motor, but also the efficiency of the same output power of the motor can be achieved, and the manufacturing cost of the motor can be greatly reduced.
