Iowa State Bulletin Reprints AIEE Paper. The Engineering Experiment Station of Iowa State College issued as its bulletin 142, 1939, “Amplitudes of Magnetomotive-Force Harmonics for Fractional-Slot Windings of Three-Phase Machines” by J. F. Calvert (A´27, M´35). The theoretical development of this work, which was carried out as an experiment-station project, was presented at the AIEE summer convention, Washington, D. C., June 1938, and published in Transactions (volume 57, p. 777–85, 1938) under the title “Amplitudes of Magnetomotive-Force Harmonics for Fractional-Slot Windings — I”. Copies of the bulletin may be obtained without charge on request to the director of the Iowa Engineering Experiment Station, Ames.
