Reflections

A New Type of A-c Motor. My experience, in common with that of my predecessors, teaches that the alternating current motor has a strong and persistent disposition to stand still, and when persuaded to motion is apt to be a sort of ‘go as you please’ machine and asserts its inherent right to turn in either direction indifferently, direction of rotation in some cases being purely a matter of chance. I shall not have much to say about efficiency, as my experiments with large machines are not sufficiently advanced to furnish any reliable data, but I will endeavor to give a general solution of the problem designed to meet the following conditions of practice: “1st. A machine that will start itself independently of the speed of the generator or number of alternations of current per unit of time.”
