DC Drag control system in theory and practice more mature, and the closed-loop feedback control from the point of view, it is dragging the exchange control system, therefore, should first master the DC system. Control of production machinery from the physical demands, the electric drive speed control system of automatic control systems, position servo system, tension control system, multi-motor synchronous control system and so many types, and are often a variety of systems by controlling the speed to achieve, so speed control system is the most basic drag control system. This article focuses on the use of power electronic learning, the achievement of a 220V, 10KW, 1000r/min irreversibility of the DC motor speed control technology .Details of irreversible DC motor speed control circuit of the detailed circuit of the control system hardware structure, working principle, the specifications of electronic components, model selection, the design of system protection, anti-hardware design. DC Motor In this paper, structure, working principle, the basic equation, mechanical characteristics and speed control methods, do not constitute reversible speed control system and control system software design part done a brief introduction Keywords: DC Motor, Speed Control, Power Electronics  目录 摘要 I Abstract II 目录 III 绪论 1 1系统方案的选择 2 1.1 直流电动机概述 2 1.2整流电路简介 2 1.3 电
