Fine rectangular wires showed poor performance, because of difficulties in building uniform insulation on fine rectangular conductors. Conventionally, round magnet wires were used for fine sizes. Mitsubishi Cable Industries, Ltd., have developed MEDIS (Mitsubishi Electro-Deposition Insulating System) which is a very unique system for producing magnet wires. We developed a fine rectangular magnet wire (\"SX WIRE\") with very good performance through this MEDIS process. We were also successful in making an ultra thin insulation with very good uniformity. The following issues are reported in this paper: fine rectangular magnet wires by MEDIS; ultra thin insulation (min. 0.001 mm) rectangular magnet wires; characteristics of ultra thin insulation wires; advanced MEDIS process for fine rectangular magnet wires; and applications and advantages of applied devices.","PeriodicalId":415071,"journal":{"name":"Proceedings: Electrical Insulation Conference and Electrical Manufacturing and Coil Winding Conference (Cat.

Accelerated thermal aging of polyester film: mechanisms affecting thermal endurance 聚酯薄膜的加速热老化:影响热耐久性的机理

Consideration must be given not only to the temperatures used in this accelerated aging, but also to the environment in which the insulation is to be functional, such as hermetic applications in various refrigerant systems. Past studies have indicated that dielectric properties are unaffected as long as the films maintain mechanical integrity. Hence, these studies have focused on the tensile strength and elongation retention upon exposure to heat in different environments (sealed in refrigerant systems or oxygen-free atmosphere, and open air). When exposed to temperatures of 140/spl deg/C, these studies have indicated that mechanical degradation mechanisms do not result exclusively from molecular weight degradation from hydrolysis or oxidation, but occur as a result of thermally induced crystallization in the film. Therefore, in addition to initial molecular weight, insulation thermal endurance also depends on film anisotropy and heat set. This investigation indicates that the direction of lowest molecular orientation (highest tensile elongation) appears to have the highest rate of embrittlement. While limited in predicting actual reliability performance of specific film types in motor applications, these results provide a means of optimizing film reliability, as, for instance, selection of a film product, the orientation of the film in a specific motor design, and/or considerations given to motor operating temperature and environment.","PeriodicalId":415071,"journal":{"name":"Proceedings: Electrical Insulation Conference and Electrical Manufacturing and Coil Winding Conference (Cat.
