The invention belongs to a sewing machine technique, especially a motor structure that can directly drive the sewing machine is designed which can improve the efficiency of power transmission, reduce energy loss in transmission process, and is characterized in that a motor rotor 6 that is fixedly connected with a sewing machine spindle 2 is designed. A V-shaped groove is designed on the sewing machine spindle 2 of the sewing machine 1, a rotor fixed screw 5 is used to fix the motor rotor 6 on the sewing machine spindle 2, and a motor front end cover 3 is fixed on a thread hole of the end face of the sewing machine 1, then a motor stator 4 is arranged in close relationship with a motor front end cover 3, and then an motor rear cover 7 is closed, four fixed screws 8 are used to fix the motor rear cover 7 with the motor front end cover 3, the motor stator 4 is wrapped, and then a hand wheel 9 is fixed on the motor rotor 6 with a hand wheel fixed screw 10 to realize the connection with the sewing machine spindle 2, finally a hand wheel cover 11 is closed, and in order to avoid external filth from entering the motor, an motor cover 12 is disposed afterwards.
Description
Technical field: [0001] The invention belongs to the sewing machine technology, and in particular designs a motor structure that can directly drive the movement of the overlock sewing machine. Background technique: [0002] Traditional sewing machines can be divided into human-driven and power-driven according to the driving mode. When sewing machines first appeared, most of them were driven by human power. With the continuous development of social productivity, this human-driven way Due to the low production efficiency, it can no longer meet the needs of social production, and the emergence of electric motors provides a reliable basis for the conversion of sewing machines from human-powered to power-driven. The drive of modern industrial sewing machines is mostly powered by electric motors, and then the power is transmitted to the sewing machine through a belt drive to realize the movement of the sewing machine. However, such a transmission mode is limited by the efficienc...
