The utility model has the advantages of achieving the same motor output power, saving copper materials, reducing the weight of the motor, and reducing costs, achieving three goals at one stroke.

Description

Industrial sewing machine motor structure wound by enamelled aluminum wire

technical field

The utility model relates to a motor structure for an industrial sewing machine.

Background technique

At present, most of the motors used in industrial sewing machines are stator coils wound with enamelled copper wires, and there is no industrial sewing machine motors wound with enamelled aluminum wires.

Contents of the invention

The purpose of this utility model is to provide an industrial sewing machine motor structure wound by enamelled aluminum wire. The slot area of the motor stator is 1.5-1.6 times larger than that of an industrial sewing machine motor with the same power, and the wire diameter is large. 1.2-1.27 times, wound with enamelled aluminum wire.

The outer diameter b of the stator is 120±5mm; the outer diameter wide side a is 110±5mm; the inner diameter c is 60±3mm; the distance i of the diagonal line at the top of the slot is 83±5mm.

The widest point d of the winding slot is 6.0-7.0mm; the narrowest point f is 4.6-5.3mm; the opening width e is 2-2.3mm; the depths g and h of the neck are 1mm and 1.5mm respectively.

The utility model has the advantages of achieving the same output power of the motor, not only saving copper materials, but also reducing the weight of the motor, and also reducing the cost, killing three birds with one stone.

Description of drawings

Accompanying drawing 1 is the plan view of the utility model stator.

Accompanying drawing 2 is a partial enlarged view of the winding groove A of accompanying drawing 1.

Detailed ways

Please refer to the accompanying drawings 1 and 2, the area of the slot 2 of the motor stator 1 is 1.5-1.6 times larger than that of the industrial sewing machine motor of the same power, and the wire diameter is 1.2-1.27 times larger. Enameled aluminum wire is used Winding.

It can be seen from attached drawing 1 that the outer diameter b of the stator is 120±5mm; the outer diameter wide side a is 110±5mm; the inner diameter c is 60±3mm; the distance i of the diagonal line at the top of the slot is 83±5mm .

The widest point d of the winding slot is 6.0-7.0mm; the narrowest point f is 4.6-5.3mm; the opening width e is 2-2.3mm; the depths g and h of the neck are 1mm and 1.5mm respectively.
