Industrial Sewing Machines
Application Notes
In recent years, the rapid development of China's garment processing industry has caused an oversupply of industrial sewing machines in China. However, with the influence of various factors such as rising labor costs, processing enterprises are putting forward higher and higher 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. Permanent magnet synchronous motors have the advantages of small size, good dynamic performance, easy control and high power density compared with traditional clutch motors. The basic control process is as follows: The 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 value of each PWM output channel through vector control algorithm and PID algorithm. The output PWM is turned on by the driver chip to the responding IGBT, which makes the corresponding winding of the motor pass current and the motor rotates continuously in the given direction.
