An application criterion of these winding types is proposed. Theoretical and experimental analyses are centred on the performances of the proposed new method of two layer winding placement-Symmetrical Placement Method (SPM) starting from the polynomial model based on the multifactorial experiment in order to replace the generally utilised methods: "lifted" and asymmetrical methods. The obtained results made it possible to highlight a lifespan variation law according to the temperature in an interval of humidity values. ER -
