High temperature induction motor preliminary sizing

This paper presents the preliminary sizing of a High Temperature (HTo) induction motor based on a copper cage rotor and a distributed winding built with an inorganic Electric Insulation System (EIS) able to withstand $500^{\circ}C$. The specific part of the design derives of the poor mechanical and electrical characteristics of the inorganic HT ° insulation materials. HT ° wires are protected by a cement and form rigid coils. The laminated magnetic core has a specific design for suiting with the rigid coils. An Electrical and thermal models are validated.
