A new algorithm for computing optimized winding configurations with arbitrary given numbers of slots, pole pairs, strands, and layers

Inhalt:
This paper presents a novel algorithm for the automatic design of winding configurations in electrical machines with arbitrary pole, slot, strand, and layer configurations. The proposed algorithm enables the rapid generation of winding arrangements that minimizes non fundamental spatial harmonics while being applicable for both concentrated and distributed windings. The introduction of a virtual current far outside the machine enables the winding design and analytic analysis of electric machines without further knowledge of the exact configuration of the winding end connections. Unlike conventional design approaches relying on empirical experience or methods with predefined values for parameters, e.g. coil pitch, such as the star-of-slots or Tingley schemes, this algorithm provides an algebraic solution applicable to integral and fractional slot configurations without restrictions. The algorithm operates on the basis of basic input parameters, including the number of poles, slots, layers, strands, and can efficiently generate designs for conventional threestrand systems as well as multistrand and multilayer windings, such as those used in hairpin configurations. The effectiveness of the approach is demonstrated through various case studies that showcase its versatility across different machine topologies. The algorithm is able to produce the expected state-of-the-art windings. A demonstration of the algorithm in form of a webapp is presented at https://windingdesigner.steeem.com/ .
