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 check possible drive regions and each operating point can be advantageous. Once a design proposal has been narrowed down, efficiency maps that are higher in accuracy are evaluated accounting for the AC loss, etc., that occurs as a result of the inverter.
Creating an efficiency map for an induction motor typically takes a considerable amount of work, but a seamless process of investigation is possible by using JMAG efficiency map studies. In addition, steady states when accounting for inverters can be obtained earlier.
This document describes how to create efficiency map studies (accuracy priority mode) using a JMAG-Designer efficiency map study (speed priority mode).
