Title:
ELECTRIC SEWING MACHINE
Document Type and Number:
WIPO Patent Application WO/2010/124626
Kind Code:
A1
Abstract:
An electric sewing machine includes a sewing machine head, a frame, double motors and a controller. The sewing machine is driven by the double motors, which means the main shaft and the bottom shaft of the sewing machine are driven respectively by the double motors. The controller synchronizes the double motors, thereby the main shaft and the bottom shaft rotate synchronously. The sewing machine is designed so that vibrations of the main shaft and the bottom shaft do not mutually influence each other, thus reducing mechanism coupling of the machine, reducing vibration and noise, and reducing error rate.
