Martin Lagler, Process Engineer ApplicationsBühler AG Uzwil, Switzerland Abstract Lost Core is a technology which is becoming increasingly more popular as the need for lightweight construction increases. The advantages are obvious: Completely new components can be developed since the use of salt cores in HPDC allows for complex internal designs. In addition, combining several components

Myeong Jin Koa, Sung-Ho Leea, Soon Sub Parka* ABSTRACT In this study, a 2.2 kW super-premium (IE4) class 4-pole three-phase induction motor was designed and developed. We compared this prototype motor with the industrial induction motors sold by leading international companies. We designed and fabricated a stator, an Al rotor, housing, bearing front and rear
