Research on power density improvement design of an HEV using induction machine based electrical variable transmission

In recent years, a new type of electromechanical energy convertor with dual-rotor structure called EVT was brought out, it can implement the function of CVT, clutch and ISG respectively and thus revealed great application potential in the development of new HEV technology research. Now the researchers have designed different type and structure of such a prototype based on different electric machine type as IM, PMSM and SRM.
