Industrial sewing machine with built-in stator winding

Abstract

The invention provides an industrial sewing machine with a built-in stator winding, wherein the industrial sewing machine is miniaturized and is low in cost. The industrial sewing machine is provided with a machine shell and a driving device embedded in the machine shell, the driving device is composed of the stator winding and a rotor, a containing chamber is integrally formed in the machine shell, an opening is formed in the position, at one end of the machine shell, of the containing chamber, a side cover is installed on the opening, the stator winding is fixed into a stator winding containing space of the containing chamber, and the rotor is located inside the stator winding and connected with a sewing machine main shaft which penetrates through a bearing installed in the chamber wall of the containing chamber and extends into the containing chamber. Due to the fact that the containing chamber is integrally formed in the shell, an electric motor serving as a power source can be arranged inside the machine shell of the industrial sewing machine, therefore no power source needs to be separately arranged outside the industrial sewing machine, the overall occupied area of the industrial sewing machine is decreased, the industrial sewing machine is integrally miniaturized, it is convenient to transport and install the industrial sewing machine, and cost of the industrial sewing machine is lowered.

Description

technical field [0001] The invention relates to an industrial sewing machine with a built-in stator winding. Background technique [0002] At present, sewing machines are widely used in the garment manufacturing industry, especially industrial sewing machines, which are more widely used in production enterprises that manufacture garments in batches. In such a sewing machine, a motor is usually installed outside the industrial sewing machine, and the output shaft of the motor is connected to the main shaft of the industrial sewing machine through a pulley to provide a power source for the industrial sewing machine, or the output shaft of the motor is directly connected to the main shaft of the industrial sewing machine , to provide power source for industrial sewing machines. [0003] However, for such an industrial sewing machine, since the motor is located outside the industrial sewing machine, the overall occupation of the industrial sewing machine is large, heavy, inconv...

AI Technical Summary

Problems solved by technology

[0003] However, for such an industrial sewing machine, since the motor is located outside the industrial sewing machine, the overall occupation of the industrial sewing machine is large, heavy, inconvenient to transport, and other accessories are required to connect the main shaft of the industrial sewing machine with the external motor, which is complicated to assemble and thus high in cost.
