First of all being magnet-free machine means that demagnetization is impossible, these electric vehicles have no-load induced voltage which can lead to high current in case of short-circuit: a perfect match that will increase performances and safety while decreasing the maintenance costs for the users. Something that is possible only by placing magnetic pole insertions in a non-magnetic disc, a new assembling technique that lets the C-cores electrically and magnetically isolated from each other so that they can be wound individually without complex winding equipment and trough automated process.
The second innovative element of this magnet-free engine is its design: a beautiful and harmonic geometrical simplicity that, once again, proves to be the winning choice allowing not only a better performance level but also, and maybe more importantly, a large scale cost effective production. With a maximized thermal dissipation and a faster and a more efficient heat transfer to the outer ambient the structure. Water cooling is not wanted for this project. Also, if we claim good thermal properties, water cooling shouldn’t be needed. Then I would say that no water cooling will be used, natural (non-forced) air cooling is enough.
