I discovered in my pile this motor:
GE A-C Motor Model 35898 For Lighting Circuits
110V 5.2A 1 phase 1/4HP 60cy 1725 rpm It was driving an old wet slo speed grinding wheel through a set of 4 jury rigged pulleys. What is strang about it is under a cover on the top is an inductor. Quite sure factory supplied. What is the inductor for? It is of laminated construction and is wired in to the motor. It appears to be of vintage 1920/1930.Any ideas? What the purpose of the inductor was? CP
