An Approach to Permeance Calculation of a Teeth Zone of a HIA Using MATLAB

The paper shows an approach to determining the permeance of the teeth zone of a Homopolar Inductor Alternator (HIA) using MATLAB tools. A HIA with a concentrated type armature winding is considered. Only the ratios of certain sizes of the tooth zone are used as initial data, which makes it possible to preliminarily evaluate the main performance indicators without resorting to the design of the entire generator. The results are presented in conditional units, which are convenient to compare with performance indicators of other teeth zones.
