A quick Campbell diagram of main magnetic force harmonics can be obtained simply based on slot/pole combination and switching strategy. This Campbell diagram can be used for comparison with measured spectrograms when there is no simulation results yet, or in early design phase of e-motors just based on slot/pole combination.

A new colormap and graphical chart has been developed for MANATEE to ease interpretations of spectrograms and magnetic force order tracking analysis.

Comparing e-NVH simulations and tests

Building an accurate e-NVH simulation model requires e-NVH testing, and comparing MANATEE software results with test results must be done carefully in order to compare what is comparable. EOMYS has written a detailed article on a methodology to correctly compare simulation and tests.

Environmental and Social Responsability

EOMYS feels close to respectful development and ecological transition with the objective of responsible engineering. In this context we decided to formulate our own Corporate Social Responsibility Chart in 2020. We will study all the social, environmental and economic concerns that are relevant for our company and work in order to establish the right actions expressing our fundamental values.

To carry out this project next year, we are pleased to welcome our new internship from February 2020, Katarina Milovanovic, coming from an engineering university specialized in environmental issues and familiar with CSR topics.

New Year 2020

The team of EOMYS wishes you all the best for this new year. Looking forward for passionate and technical challenging projects coming for sure next year!
