High temperature induction motor preliminary sizing

This paper presents the preliminary sizing of a High Temperature (HT°) induction motor based on a copper cage rotor and a distributed winding built with an inorganic Electric Insulation System (EIS) able to withstand 500°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.
