【摘要】 目前交流电动机普遍采用线控的调速方式,但在一些特殊场合下,为方便操作和提高效率,对交流电机的速度控制采用无线遥控方式。通过对交流电机调速以及变频器的变频原理分析,确定了利用单片机对交流电机实行遥控控制的方法。文中介绍了基于MSP430单片机的交流电动机遥控系统,并给出了硬件和软件设计。更多还原

【Abstract】 At present the common method of motor speed control is wire control.But in some special situations,for convenience and efficiency,telecontrol is used for speed control.Through analysis for principle of motor speed control and converter,the method is determined,which is telecontrol by single chip microcomputer.The telecontrol system of alternating current motor based on MSP430 single chip is presented in this paper.Also the hardware constitution and design of software are given in detail.更多还原
