Abstract

Recently due to the market expansion of EV, more efficient motor gearbox design process is desirable. For identifying noise issues early in the design stage, it is necessary to consider interactions between gearbox and motor. A new software interface between JMAG and Romax software has been developed to simplify the data transfer between electromagnetic and NVH analysis as part of an end-to-end analysis process.
