Discussion on “comparison of two- and three-phase motors,” at Milwaukee, Wis., May 28, 1906

A. S. McAllister: The author says that the magnetizing current in a three-phase motor is approximately 15 per cent. more than that in a two-phase motor, but that when expressed in per cent. of the full load current the magnetizing currents of the two motors are equal. These statements are based on a study of the distribution of the primary coils, of the change in the value of the magnetizing current, and of the fluctuation in magnetism produced thereby.
