Abstract
991,186. Transformers; electromagnets. F. KNOBEL. Feb. 20, 1962 [Feb. 21, 1961], No. 6587/62. Headings H1P and H1T. A magnetic core, which is magnetized by a longitudinal winding 4, consists of an inner rodshaped part 1 and an outer tubular part 2, the latter being formed by coiling a strip of ferromagnetic material. The coil 2 may be formed continuously or in a plurality of portions and its cross-section may be circular, oval or square with rounded corners. The inner core part may be formed of a stack of longitudinal laminations 1 (Fig. 4) the thickness of the stack being double the width of the strip used for the outer part and the width of the individual laminations being such that a substantially uniform air gap 8 is left between the edges of the laminations and the inside of the outer core part. The inner core part may alternatively consist of a stack of transversely extending laminations. A fine adjustment can be made to the electrical characteristics of the coil by inserting ferromagnetic wires 7 in the cavities 6 in the core. Insulation 5 is provided between the inner core part and the winding and plastic members 3 are used to hold the laminations of the inner core together.
