Abstract
An apparatus and method for fabricating a stator of a super-high-speed induction motor, in which the process of loading a stator on which a coil is completely wound into a mold, injecting a functional resin into a chamber, converting the inside of the chamber into the vacuum state, and pressurizing the inside of the chamber is carried out so that bubbles are removed from the inside and the surface of the functional resin and the functional resin is completely filled between the inner circumference of the stator and the inner circumference of the mold, thereby maximizing heat conductivity and insulation, preventing the stator from deteriorating, and improving the performance and endurance of the super-high-speed induction motor. In addition, since the vacuum step and the pressurizing step include heating the mold, in the vacuum step, the viscosity of the functional resin can be decreased so that the process of removing gas inside the stator can be efficiently performed and the solidification time of the functional resin can be decreased so that the working time can be decreased, and in the pressurizing step, the molding that is under pressing force is completely solidified.
