This paper presented the design of DC motor speed regulator based on LM324,detailed circuit theory chart and its illustration. The speed feedback designed includes soft starting, voltage negative feedback, current positive feedback, post current cut-off protection and differential correction circuit and new simple efficient technology of pulse block and magnetic lose protect. The performance index reached could satisfy completely the demand of DC motor speed regulator when it was used in the product processes of food, drugs and light industry and chemical industry. It will be used widely in those industries because of its reasonable structure, stable performance and low cost.
