Abstract

Cars contain many motor products, which consume electric power. Development of more efficient motors will decrease the load on the alternator, resulting in improved fuel economy and reduced emissions of exhaust gas. New technology that can be used to study the distribution of core loss in the core will be useful for designing more effective motor products. This report introduces a new method for examining the distribution of the core loss. In this method, the distribution is calculated using an inductive technique that utilizes experimental data.
