A rare, early 20th century, commutating, single phase, 25 cycle, alternating current motor, likely of the repulsion type, an early marker of vastly changing times to come, following the first wave of home electrification.

\u2013 A rare example of an early communtating, alternating current motor design, engineering and manufacture, likely of the repulsion motor genre. See references 1, 2 and 5 for discussion of design and operation of early 20th century communtating AC motors.
\u2013 An early marker of vastly changing times to come, following the first wave of home electrification technology. An icon, it would herald the coming invasion of the Canadian home by electro-motive technology, starting in central Canada in the 1920\u2019s.<\/p>","protected":false},"excerpt":{"rendered":"
