Abstract :
This paper presents a slot leakage model for stator windings having a fractional number of turns per slot. The results are compared with finite element simulations and measurements using search coils in a prototype machine. Although the slot leakage model predicts the leakage correctly in the slot bottom, the model cannot be used on its own for the slot top since the zig-zag leakage was very pronounced just below the slot wedge.
