CORE LAMINATIONS, PARTICULARLY FOR TRANSFORMERS

摘要

Dr. Karl Philberth A b s t r a c t Fig.1 and Fig.2 Core laminations of the UI or EI type for iron cores, particularly for transformers, having two or three legs of equal length e and equal width f, spaced mutually apart by the same distance h, wherein the width c1 of the jointlessly connecting yoke is greater than the width c2 of the parted yoke, using the following dimensions: 1.1f ? c1 ? 2.1f and 1.0f ? c2 ? 1.5f and 0.1f ? c1-c2 ? 0.6f. Preferred dimensions for a waste-free UI shape and a suitable EI shape are: c1 = 1.4f; c2 = h = 1.2f; e = 3.2f. Preferred dimensions for a waste-free EI shape are: c1 = 1.5f; c2 = h = 1.2f; e = 2.7f.
