A New Method for Sewing Machine Starting Based on BLDCM

According to the characteristics of the sewing machine, a new starting method was presented on the basis of the analysis on the characteristics of application of brushless DC motor, which is the three-step starting technique during the sewing machine starting. The experimental results indicate that this method significantly enhances the speed of starting and improves the reliability of the equipment, as well as more adaptive performance and better in dynamic response.
