In this paper, the study presents the development of 34kW class cryogenic induction motor using LNG Pump. Operating temperature of an induction motor using LNG Main Cargo Pump is at −163℃. Due to variation of the resistivity, these motor have different torque characteristics. So, it should design to considering the resistivity change. The most important consideration of induction machine operating is cryogenic temperature. If the temperature rise, LNG is vaporized. it is a major cause of pump failure. There are several causes of heat source like coreloss, hysterisysloss, copperloss. This paper analyzed the thermal distribution of the induction motor at rated speed operation.
