Resumen
CASTRO-HEREDIA, Luis Carlos y OSLINGER-GUTIERREZ, José Luis. Calculation methodology of the harmonic magnetomotive force and its relationship with the sequence components slot fem. Ing. Univ. [online]. 2013, vol.17, n.2, pp.339-354. ISSN 0123-2126.
In this paper we propose a new method to calculate the relative harmonic spectrum of the magnetomotive force per phase, based on the generalization of calculating the winding distribution factors and including the Fourier matrix F and matrix C of the winding spatial representation in the calculations. In the proposed methodology, the winding distribution factors are calculated taking into account all poles of the machine and not only a couple of poles, as illustrated in some textbooks. In addition, in this article we analyzed the unbalanced regime windings through the calculation of the components of the electromotive force sequence in empty slot, and these components were related to the harmonic spectrum of the magnetomotive force per phase in symmetric regime. The calculation methods were implemented and validated in a Java application. From the results we proposed a method for calculating the magnetomotive force harmonic spectrum by phase which may be applied to windings of any spatial distribution, as well as a methodology to represent an asymmetrical system of m phases, through sequence components of electromotive force of slot in vacuum.
