Electric Motors \u2013 Single Phase, Repulsion Induction and Repulsion Motors<\/h3>\n\n\n\n

An early 20th century, 25 cycle, repulsion induction motor with historic, innovative, first generation, vibration isolating, rubber motor mounts, a significant step in helping to reduce the noise level in the kitchen, resulting from the introduction of motorized machinery, Delco, Circa 1932. [see also ID# 299, 301, 302]<\/p>\n\n\n\n

Features:<\/strong>
\u2013 Early 4 point, innovative, vibration isolating motor mounts<\/p>\n\n\n\n

Technical Significance:<\/strong>
\u2013 Stands as an exemplar of the dissemination of 4 point rubber insulating motor mounting technology in the early 1930\u2019s adopted here by Delco, a division of Frigidaire \u2013 see also ID# 297
\u2013 Repulsion induction motor technology was above all a marvel of its time, a technology born of both science and the consumer market place, a classic formula for the innovation and diffusion of popular technology, throughout the balance of the 20th century and on in to the 21st. Scientifically, the work of Faraday and many others laid much of the theoretical foundations for electromagnetic devices, the marvel of the early 20th century [much in the same way digital devices became the marvel of the early years of the 21st]. The wonders made possible by alternating current energised, rotating magnetic fields and the electric and magnetic circuitry that made them possible would soon be exploited by those interested in their application in applied electro-motive technology, including Steinnmetz and others.
