Abstract

The voltage distribution inside a machine's winding is analyzed in this paper. The use of a simple distributed parameters coil model allows to predict, in a qualitative way, the value of the peak voltage as a function of the winding length. Thanks to a simple algorithm, the voltage peak distribution is analyzed as a function of the coil constructive parameters like the capacitance-to- ground and the inter-turn capacitance. Remarks on the effects of the insulation thickness variation for the winding are made. Simulation results and Finite Element Method (FEM) analysis are presented for different cases.
