Abstract

204,433. Juhlin, G. A., and Metropolitan-Vickers Electrical Co., Ltd. July 7, 1922. Pole-pieces.-The pole-cap of a salient-pole rotor is attached to the polar projection by means of a dovetail joint extending along the pole, and the parts are provided with mutually engaging spigots or projections so as to strengthen the portions weakened by the provision of the dovetail groove. The pole-cap 4, Figs. 1 and 2, consisting of plates or laminµ, has a groove 6 in which engages a dovetail 5 on the core 2. The core has projections 16 engaging with projections 17 on the cap, which although normally weakened along the centre line 15, is correspondingly strengthened. In a modification, the dovetail is formed on the cap and fits into a groove on the pole, and the arrangement of projections 16, 17 shown in Fig. 2 is reversed. The end plates 7 supporting the polecap and coils are formed with projections 11, which are held by projections 10 on the pole 2. Flanges 14 may also be provided to support the coil.
