Abstract

1418903 Electromagnets LUCAS ELECTRICAL CO Ltd 24 April 1973 [3 May 1972] 20679/72 Heading H1P [Also in Division H2] A magnetic pole for electromagnetic excitation comprises a body 12 (Fig. 1) with an integral shoe 13 of greater width, formed from a single mild steel strip which is corrugated and longitudinally compressed so that the convolutions are in facial contact to define a stack; the lengths of the corrugations adjacent one end being greater than these adjacent the other so that the shoe 13 and body 12 are defined on compression. In a modification a part of the pole shoe is displaced in the direction of the pole depth by correspondingly shaping the strip adjacent the end from which the pole shoe is formed. (Fig. 2, not shown). For use in the interior of the cylindrical yoke of a dynamoelectric machine the pies are formed to have a part cylindrical profile. In an electromagnet, the poles are diametrically positioned within a cylindrical magnetizable yoke 15 (Fig. 3) so that the shoes define a part cylindrical surface through which a shaft extends axially to slidably carry an armature, while the yoke or poles carry an exciting winding. On energization the armature is moved axially along the shaft towards the shoes. The pull on the armature may be positionally graduated by stepping the pole shoes.
