Установлено, что оптимальная конфигурация достигается при угле охвата магнитов 72° и воздушном зазоре 0,85 мм, что подтверждает необходимость применения современных оптимизационных методов для поиска нетривиальных технических решений.</p><p>Заключение.

It was found that the optimal configuration is achieved with a magnet coverage angle of 72° and an air gap of 0.85 mm, which confirms the need to use modern optimization methods to find non-trivial technical solutions.</p><p>Conclusion. The results obtained are of practical importance for designing energyefficient motors, reducing development time.
