When the computerized embroidery machine is working, the pattern code is stored in the memory RAM of the controller in advance. In the embroidery process, the position detection device detects the position of the needle at any time. When the needle moves to the position below the cloth surface, the computer takes out the data of a needle stored in RAM, analyzes and processes it, and forms the control data of the stepping motor. Ready to run. When it is detected that the needle leaves the cloth surface, it will output to the stepping motor according to the prepared control data to complete a needle movement. And realized the synchronous operation of the power motor and the control motor 1-27mm. We noticed that the range of stitch length is between 0.1-12.7, that is, the running cycle of each stitch of the stepper motor is 1-127 steps. The operating speed of the power motor must meet this condition. However, the speed of the power motor cannot be limited by 127 steps per stitch, which will inevitably reduce the efficiency of the entire machine. Therefore, the power motor must be operated at a variable speed.
