Discussion on “the squirrel cage induction generator” (Hobart and Knowlton), “single-phase induction motors” (Branson) and “motor starting currents as affecting large transmission systems” (Lincoln). Boston, Mass.

Lee Hagood: My remarks will be confined to the question of exciting current in connection with Mr. Hobart´s and Mr. Knowlton´s paper. As you will see from reading their paper, the matter of exciting currents bears very much on the question of air gaps. To some extent, the amount of exciting currents required may appear to be a very great objection to these machines. I wish to make the point that neither the design of the machine nor its application should be very much restricted on account of exciting current.
