With the continuous development of science and technology subjects and the corresponding higher education courses to update teaching content, the traditional instruments revealed the growing number of deficiencies and shortcomings. In order to improve the experimental conditions, experimental teaching methods to improve and update the contents of the experimental teaching to improve the experiment the level of teaching curricula, the introduction of the virtual instrument experimental teaching has become a trend. This article is based on virtual instrument applications in the electrical design. Virtual instrument of modern computer technology and equipment, a product of the combination. The introduction of virtual instrument technology to experimental teaching, the purpose is to update the laboratory equipment, laboratory equipment to reduce acquisition cost, reducing the experimental measurement in the process of human error, improve the accuracy of experimental measurements; stimulate students in learning self-promote students hands-on experience and strengthen their sense of innovation of great significance to the area. In this paper, the United States, NI's Labview 7.1 software development platform to the motor mathematical model based on the overall virtual machine, the process of establishment of electric braking VI of the current model, which can be applied to the experimental design of the motor teaching experiment. This paper first introduces the topic of the research background and significance of the study and presented the main contents of this article; and then introduced the subject of the research tools - Virtual Instrument, the definition of its form, function, characteristics and development prospects; then introduced a virtual instrument development environment - Labview software, summed up the characteristics of Labview software, a simple introduction to the operation of its tools, in addition to the G programming language was introduced; next to the data acquisition and the associated the signal conditioning, instrument drivers, the basic concept of the trigger buffer described; and then focusing on the design of the experiment - based on the electric brake Labview observation and analysis process, from the model, functions, the program shows that the experimental results aspects in detail; Finally, the conclusions of this article, summed up the entire design.
