In this method, one can determine optimal shapes of machines that are composed of various materials, such as iron, magnetic, and nonmagnetic material. The present method is applied to the optimization of the average torque for interior permanent magnet motor to determine the distributions of magnetic core and flux barrier as well as magnets. The optimization results show that average torque can be improved using as small amount of magnet as possible. In addition, the characteristic of the present method is discussed in detail.IEEE2015-03engjournal articleAMhttp://hdl.handle.net/2115/59622https://doi.org/10.1109/TMAG.2014.23599720018-9464IEEE transactions on magnetics5137202604https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/59622/1/70053.pdfapplication/pdf311.47 KB2015-03
