Abstract: The thesis is basd on the national science and technology support project name by “the research and development of efficient sewing equipment servo control system”. The paper made an indepth research in industrial buttonhole sewing machine drive system. Firstly established the servo motor′s mathematical model, Secondly introduced a method based on the motor control technology of space vector pulse width modulation ( SVPWM ) and discussed the SVPWM control mode in detail, and gave the implementation process.
Key words: industrial buttonhole sewing machine; spindle servo motor; the control principle; mathematical model
