1、直驱电机的改进，大大减少了机械结构的故障率；

2、采用伺服电机直接驱动，最高缝制速度可达2000r.p.m;

3、采用大功率电磁铁抬压脚，能使抬放压脚更灵敏；

1,direct drive motors improve,greatly reducing the failure rate of the mechanical structure;

2,servo motor direct drive,maximum sewing speed up 2000r.pm;

3,using high-power solenoid presser foot,can put the presser foot lift more sensitive;
