现阶段对异步电动机进行转角控制逐渐受到人们的关注,为实现对三相异步电动机转角的准确控制,本文首先详细分析了异步电动机的数学模型,然后采用PLC对异步电动机进行控制,实现了较好的控制效果。现阶段虽然很多领域采用步进电机进行转角的准确控制,但异步电动机与之相比具有功率大、价格低廉、可靠性高的优点,因此对三相异步电动机进行转角的准确控制具有重要意义。
At this stage, the control of the rotation angle of induction motor is getting more and more attention. In order to realize the accurate control of the rotation angle of the three-phase induction motor, this paper first analyzes the mathematical model of induction motor in detail and then uses PLC to control the induction motor. The control effect. Although stepping motors are used to accurately control the rotation angle in many fields at this stage, asynchronous motors have the advantages of large power, low cost and high reliability compared to them. Therefore, accurate control of the rotation angles of three-phase asynchronous motors is of great significance.
