| The
here reproduced models are not those originate them, planned and
constructed from G. Ferraris, which went nearly completely destroyed in
the fire of the “national Exposure electrical
worker” of Como, 1 ' 8
July 1899 [*], with the relics of Alessandro Volta. The little singed
rests, were
placed in the old study of G. Ferraris, conserved in the Polytechnic of
Turin and went definitively destroyed in the fire of the Polytechnic,
as a result of a strafing, 9 December 1942. These
models were reconstructed, after the fire of 1899, under the Fat guide
of prof. Guido, successor of G. Ferraris to the school of Turin and
perhaps, second an oral tradition, from the same laborer who had made
the first apparatuses 14 years before. Two of they still carry the
cards written from the prof. Fat. They escaped to the fire of 1942
because they were conserved to National the Electro technical Institute.
All
the models of the first motors to rotating field of today existing G.
Ferraris, also abroad and also those of the Ferraris museum to Livorno
Ferraris, are copies of those here reproduced. The photography executed
before 7 reproduced March 1897 in the “Actions of the Italian
Electro technical Association” - vol. - 1897/98, are the only
remained
document of the configuration of the relics originate them.
[*]
In the year the 1899 models (with other apparatuses, relics and papers
of Galileo Ferraris) were sent to the “National Exposure
Electrical
worker and of serici Products”, organized to Como in order to
celebrate
the centenarian of the discovery of the battery of Volta. |
