The work principle of electric power press brakes based on transducer was given. As a result of the wide practicality of the press brake, a control system based on electromotion was developed. The principle of the control system and the key techniques of hardware and software in control system were described. In the hardware part, ISA industrial control cards and serial port were studied, in the software part, the delamination of WDM(Windows Driver Model) and the communications between the application layer and kernel layer investigated. The arithmetic of control system was described. It determined the stability and delicacy of electric power press brake control system capability and achievd hardware devices independency. In the treating process of the control system, the efficiency and precision were shown.
