Abstract

Шихтованный сердечник включает в себя множество листов электротехнической стали, которые уложены пакетом друг на друга. Все наборы листов электротехнической стали рядом друг с другом в направлении укладки закреплены друг к другу в шихтованном сердечнике. Некоторые наборы листов электротехнической стали из всех наборов листов электротехнической стали крепятся, но не приклеиваются друг к другу, и оставшиеся наборы листов электротехнической стали приклеиваются, но не крепятся друг к другу.
