Electric Motors – Single Phase, Repulsion Induction and Repulsion Motors
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]
Features:
– Early 4 point, innovative, vibration isolating motor mounts
Technical Significance:
– Stands as an exemplar of the dissemination of 4 point rubber insulating motor mounting technology in the early 1930’s adopted here by Delco, a division of Frigidaire – see also ID# 297
– 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.
