Discussion on “fractional pitch windings for induction motors”, and “zigzag leakage of induction motors”, at Niagara Falls, N. Y., June 28, 1907

Have experiments been made to determine the relative importance of the three kinds of leakage found in induction motors? 1. The leakage across the slots. 2. The leakage across the gap, or so-called zigzag leakage. 3. Leakage in the end-connections of the stator winding.
