Abstract
Honda aims to realize carbon neutrality for all products and corporate activities Honda is involved in by 2050, striving to eliminate carbon emissions from power sources of a wide variety of products. We have been promoting the efficiency of the development process using CAE in strengthening electrified vehicle development in the automobile business. In this presentation, we introduce our initiative in the evaluation methods utilized in the noise and vibration development for a motor in the drive-unit by linking Romax and JMAG-Designer. The methods consist of the evaluation of excitation force by resolving rotational and spatial orders in the magnetic excitation force, and the analysis of response contributions from the components of torque ripple, radial, and tangential directions, which are considered the main magnetic excitation force.
