In recent years, the rapid development of China's garment processing industry has led to a shortage of industrial sewing machines. However, due to various factors such as rising labor costs, processing enterprises have put forward increasingly high requirements for the performance of industrial sewing machines. At present, industrial sewing machines with permanent magnet synchronous motors as the mainstream power unit are rapidly occupying most of the market. Compared with traditional clutch motors, permanent magnet synchronous motors have advantages such as small size, good dynamic performance, convenient control, and high power density. The basic control process is as follows: DSP determines the current position of the rotor and calculates the current speed of the motor based on the captured Hall position signal, and calculates the effective values of each PWM output channel through vector control algorithm and PID algorithm. The output PWM is activated by the driving chip to respond to the IGBT, causing the corresponding winding of the motor to pass current and the motor to continuously rotate in the given direction.
