Application of DC Motor Digital Speed Control System in Submerged Arc Welding Machine


Article Preview

Abstract: In the current domestic control system of submerged arc welding machine, most walking DC motor speed control uses the method of analog control pulse width modulation (PWM), which has a complex circuit, high failure rate and is inconvenient to use. For this phenomenon, DSP (TMS320F2812) disc is used to build a digital control system, and replace the traditional analog controller, allowing the weld control system more simple and practical. The main content of this paper is the hardware circuit design and software algorithms programming of digital control DC speed control system. Tested by experiment, this digital control system can replace the weld analog control system, enabling the motor to have good control performance at low speed thereby enhancing the welding effect of submerged arc welding machine.
