Electric machines project activities using mathcad E-book

Recent software advances have made a wide variety of computer-based learning tools available for teaching induction motor theory. These tutorials and visualizations typically target specific fundamental topics, require detailed knowledge of the development software to produce, and provide a rudimentary connection with other relevant practical topics like cost of operation. These fundamental applications also do not allow them to explore alternatives within the presented material. MathCAD® E-books provide a platform for student learning which avoids the shortcomings of other instructional software and combines it with actual laboratory measurements to enhance students' learning experience. This paper presents assessment results for an E-book application that combines induction motor theory with engineering economics in a novel format. The study exposed students to several different pedagogical approaches and evaluated student learning with several different assessment tools. These approaches included traditional lecture/written homework, in-class introduction and application of the E-book, self-study using the E-book, and E-book simulations. Laboratory measurement of induction motor performance under various load levels and load types links theoretical analysis and practical motor applications. The project includes a detailed economic analysis of an induction motor application that simulates the work of practicing engineers. A data from a pilot study shows this to be a promising presentation method.
