【摘要】 Scott变换是指通过简单硬件方式实现三相/两相电压的变换,在"电机学"课程里是非常重要的,但授课中一般不进行介绍。为了拓展学生的知识面,培养学生的创新意识和动手能力,本文介绍了一个基于Scott变换的设计实验,通过观测李萨如图形来加深对两个相信号合成磁场性质的理解。文中介绍了实验设计的具体内容,包括理论分析、实验电路和实验测试等。实践证明,这样的设计创新实验对培养学生的科技创新能力是非常有益的。更多还原

【Abstract】 Scott transform is very important in Electric Machinery which means to realize a three phase/ two phase voltage transform through simple hardware.It is not introduced in class teaching generally.In order to extend the students’ knowledge and improve their creative ideas and operation ability,a designed experiment based on Scott transform is introduced in this paper.Through the experiment,students can understand the resultant MMF of two phase voltages under different symmetry conditions by observing Lissajous waveforms.Academic analysis,experiment cicuit and its test are concerned in this paper.It is proved that this kind of experiment is very beneficial for the inspiration of students.更多还原
