Study on downsizing techniques for conventional motor with solid insulation system

This paper describes a feasibility study of a solid insulation system applied downsized motor. A large amount of insulation resin was employed to replace structural metal materials used in conventional motors. The optimal heat design, mechanically stable structure, and proper insulation resin are proposed and discussed. A prototype motor was manufactured, and results of a basic insulation test, temperature rise test and noise test are presented.
