摘　　要：对“电工学”课程实验中的电机正反转控制和“Y-△”启动控制,分别用接触器控制和PLC的计时器控制,并对两种方法进行了对比研究;为解决接触器控制中触点竞争问题提供了一种新思路。通过这种实验,极大地激发了学生学习的兴趣,培养了学生的实践能力和创新能力,提高了实验教学质量。The control method of electric machine positive-negative rotating and ＂Y-△ ＂starting in electrics experiment are studied by means of relay-contactor control and PLC control. A new control method is proposed to mitigate contact competing by means of PLC timer program. Though this method, it can much motivate students＇ interesting, and develop students＇ experiment ability and innovation ability. It may offer some way for improving experiment teaching.
