The paper deals with the design of irregular AC windings by a new method. The new method is based on the notion of “local density of conductors”. Design of the interspersed winding 1–3–1 is shown as an example of using this new method. This type of winding can be used to reduce higher harmonic components of magnetic flux density in the air gap, mainly the fifth and the seventh harmonic. This new method...
The paper describes a new universal infinitesimal method, which enables the calculation of self and mutual inductances of arbitrary AC windings. The method is based on the notion of the local angular density of conductors n(α) = dN(α)/dα. It will be proved the proportionality B(α)≈ ∫n(α)dα for the magnetic flux density in the air gap. The function n(α) can be arbitrary, i.e. of continual or impulse...
