Recent advancements of permanent magnet (PM) materials and solid-state devices have contributed to a substantial performance improvement of permanent magnet machines. Owing to the rare-earth PMs, these motors have higher efficiency, power factor, output power per mass and volume, and better dynamic performance than induction motors without sacrificing reliability. Not surprisingly, they are continuously receiving serious considerations for a variety of automotive and propulsion applications. An electric vehicle (EV) requires a high-effficient propulsion system having a wide operating range and a capability of generating a high peak torque for short durations. The improvement of torque-speed performance for these systems is consequently very important, and researches in various aspects are therefore being actively pursued. A great emphasis has been placed on the efficiency and optimal utilization of PM machines. This requires attention to many aspects related to the machine design and overall performance. In this respect, the prediction of iron losses is particularly indispensable and challenging, especially for drives with a deep field-weakening range. The objective of this paper is to present iron loss estimations of a PM motor over a wide speed range. As aforementioned, in EV applications core losses can be significant during high-speed operation and it is imperative to evaluate these losses accurately and take them into consideration during the motor design stage. In this investigation, the losses are predicted by using an analytical model and a 2D time-stepped finite element method (FEM). The results from different analytical approaches are compared with the FEM computations. The validity of each model is then evaluated by these comparisons.

The qualitative effect of class is influenced by the instructor's class design and operation method, but it comes from motivating students to actively participate in class and utilizing potential qualities that lead to student-centered learning. Students' activities and the quality development of class participation can be utilized in presentation-based classes. This could be confirmed through the presentation classes in English language curriculum applied to English major students in Korea. In other words, with presentations conducted in language-theoretic classes such as phonetics/phonology, and syntax, it turned out that immersion in learning, concentration on class, and motivation for learning can be improved, developing systematic self-directed learning ability and cooperative mutual communication ability. Instructors need to lead the direction and design of the classes, but the actual educational effect depends on how students accept the academic tasks, how well they understand the learning contents, and how well they can systematically transmit them to others. In this respect, this study aims to investigate that learner-centered presentation classes contribute to making learners develop their competencies in class design, data utilization, imparting knowledge, and communication, which would bring about the improvement of learning quality and educational effects.
