摘　　要：交流电机比直流电机经济耐用得多,因而被广泛应用于各行各业。在实际应用场合,往往要求交流电机能随意调节转速,以便获得满意的使用效果,但它在这方面比起直流电机而言就要逊色地多,于是不得不借助其它手段达到调速目的。本文通过食品输送带的变频控制方案来了解变频器的最简单应用。AC motor, which is widely used in the various industries, is much more durable and economic than DC motor. In the practical applications, we often require the adjustable speed for AC motor in order to get the satisfactory results. But it is not good in this aspect compared with DC motor. So we have to use the other means to achieve the speed adjustment goal. In this paper, AC inverter is used for the food conveyor belt drive control to understand the simplest applications.

关 键 词：变频器 交流调速 直流调速
