Electric Motors – Single Phase, Repulsion Induction and Repulsion Motors
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. It would herald the coming invasion of the Canadian home by electro-motive technology, manufacturer’s name partially obliterated, date unknown. [se also ID# 304]
Features:
– Oiler cap marked “The OK Mfg Co. Dayton O.”
– 6 inch pig tail leads illustrating electrical wiring practice of the times
Technical Significance:
– 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.
– 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’s.
