Motor design conventionally sees a large number of general design proposals being investigated until they are narrowed down to prospective designs that satisfy requirements. An efficiency map is drawn for each motor design proposal in this narrowing-down process. Using efficiency maps to confirm possible drive regions and each operating point can be advantageous. Once a prospective design has been narrowed down, AC loss that considers inverters can be taken into account, and efficiency maps of a higher accuracy are created and then evaluated.
Creating an efficiency map typically takes a considerable amount of work, but a seamless process of investigation is possible by using JMAG efficiency map studies.
This document describes how to create efficiency map studies (accuracy priority mode) using a JMAG-Designer efficiency map study (speed priority mode).
