Integrating the Advantages of Hardware and Software Tools into An Induction Machine Education

Abstract

This paper develops exercises on hardware and software tools for enhancing an induction machine (IM) education. Firstly, the hardware tools mainly consisting of a wound rotor induction motor and a digital oscilloscope are used to demonstrate the operating principles of the IM through an open-circuit, a no-load, and an on-load test. Typically, the teaching of the relationship between stator frequency and rotor frequency is taught by a pure theorem. In this paper, it is directly measured through various exercises. Secondly, the software tools using MATLAB are used to build the simulation tools for IM analysis. Typically, the IM block in Simulink is used to evaluate its performances. In this paper, the simpler simulation IM block is presented for a steady state analysis. It has been proposed with the goals of making it as versatile as possible for students to learn independently about topics such as the effect of voltage input/slip on the performance of the IM. The uses of the proposed exercises on the hardware and software tools have led to a real breakthrough for an IM education. The proposed methods have been successfully integrated into the IM education at Kasetsart University Sriracha Campus.
