Abstract

The invention discloses a motor structure of a one-piece industrial sewing machine. The motor structure comprises: a motor stator assembly, which is arranged in a handpiece of the industrial sewing machine; a motor rotor assembly, which is arranged on a main shaft of the industrial sewing machine. The motor stator assembly is sleeved on an outer side of the motor rotor assembly. The motor stator assembly is connected with a power supply through a motor outgoing line. Compared to the current product, in the motor structure of the one-piece industrial sewing machine is not an individual part. The motor is one part of the handpiece of the sewing machine. An inner cavity space of the handpiece of the sewing machine can be fully used. The inner cavity becomes the part of the motor. A purpose of the invention can be realized.

Description

technical field [0001] The invention relates to the technical field of industrial sewing machines, in particular to a motor structure of an industrial sewing machine. Background technique [0002] An industrial sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material. Industrial sewing machines are widely used, and the existing installation and transmission methods of industrial sewing machine motors mainly include the following: [0003] First, the way of transmission by belt (triangle belt): the motor is installed under the table, and is driven by the belt between the motor and the sewing machine. The characteristic of this structure is that the distance between the motor and the head pulley can be relatively large, but this method is greatly affected by the tightness of the belt installation, and the transmission efficiency is slightly low; the transmiss...
