摘　　要：电弧喷涂技术广泛应用于表面工程领域，能否等速同步送丝是其技术关键．提出了一种送丝电机调速系统，在分析电弧喷涂原理的基础上，通过采用由ＰＷＭ 调速、光电测速的ＰＩＤ 自动调节系统，实现了等速同步送丝，送丝速度可以采用数字指示并可预调．该电路成本低，性价比高，是一种值得推广的电路．This paper deals with synchronous wire feed circuit of arc spraying.Based on principles of arc spraying system,a PID automatic adjusting system by PWM regulating speed circuit and light-electricity measuring speed cricuit is developed.The experimental results show that the feed rates of two wires is equal with each other.The wire feed rate whose regulated range is wide,could be digitaly displayed and regulated beforehand.The cost is low,and the ratio of property to price is high.It is a kind of circuit worth popularizing.
