Electric motors for the farm (single phase)
1940
Beaty, H. H. | Thomas, W. A.
"A quarter-horsepower motor can operate any machine that can be manually operated by an able-bodied man. Such a motor can drive any farm machine ordinarily turned by hand at a cost of about 1 cent per hour for electricity. A 1/4-housepower motor costs from $5 to $18; a good reliable heavy-duty motor costs only $11.50, and it will last for may years. In this time it will do dozens of chores such as pumping water, turning separators, grinding corn, driving farming mills and shelling corn. With proper care electric motors will give years of low-cost, trouble-free service, but with improper care a motor may wear out in a year or burn out in a few minutes. Unlike a gasoline engine which stalls when overloaded, the electric motor will continue to do work even when overloaded and run until its winding insulation goes up in smoke."--Page [365].
