Abstarct: Today high temperature superconductive (HTS) tapes have taken sufficient potential to penetrate electrical machines markets duo to their fascinating electrical properties. In order to zero electric losses in HTS windings, it is possible to reduce motor's total weight by using tenacious non-magnetic materials. In comparison by heavy magnetic materials such as steel, non-magnetic materials are so light. Here a new structure for 1.1Mw industrial HTS synchronous motor was introduced, numerical FEM analysis was performed on and its main specifications were obtained. Unlike air-cored HTS synchronous motors, in compound model large amount of heavy iron used in rotor construction was replaced with light non-magnetic materials such as G-10 fiberglass. This, reduced rotor weight up to 50% in comparison by similar completely iron made one. Furthermore, even for non-improved model, rotor bearings sustain less pressure and their working stability would be increased besides total weight reduction in over 97% efficiency condition respectively.
