| 1. Computer-controlled servo motor for fast start-up, smooth and quiet operation, with excellent performance and a maximum sewing speed of 3000rpm. 2. Visual operation panel with voice broadcast for buttons, switchable Chinese/English display, and stitch counting function; 3. Start/stop control of the feed cam function via photoelectric sensor, making adjustment simpler and more convenient, resulting in beautiful and stable stitching; 4. Servo motor driven presser foot lifting for more precise positioning and quicker response; 5. Servo motor driven guide rail for vertical sliding, enabling continuous blade lowering, increased blade height, and preventing blade collision with presser foot or blade jamming; 6. Equipped with thread breakage electromagnetic sensor; when thread breaks (as shown in the right image), the machine will not cut the thread or lift the presser foot, thereby avoiding fabric waste. |  |
