Electric vehicles and electric drives of essentially new type
Journal Title: Invention Journal of Research Technology in Engineering & Management - Year 2018, Vol 2, Issue 4
Abstract
The principal type of energy for mankind, i.e. for heat and light production infrastructure, for supplying maintenance of transport and industry work, is the electric power. About 90% of the electric power is produced by EG (EG – the electric generator), about 60% of which are used from EM (EM – the electric motor). EM (EM – electrical machines, i.e. EM and EG, currently has two directions of development – as SA-EMn (SA-EMn separate object of general purpose industrial use, in abbreviated form – SA-EMn) and inside of electric drive OMEM (OM-EM - electric drive). At the same time depending on convenience of description, the electric drive can include the operating member of cars or not. Nowadays SA-EM and OM-EM, have substantial drawbacks and limitations. SA-EM – bulky; material-intensive; having small efficiency, especially widely used medium and low powered EM. OM-EM – have low energy efficiency. For example, the existing electric vehicles have to carry approximately 500 kg of accumulators. For cooling of accumulators and electric motors it is used powerful cooling systems, i.e. much of energy is lost inefficiently
