Stator windings of asynchronous electric motors. - Zernograd: VNIPTIMESKH, 2001, p.44).

Недостаток известной обмотки заключается в том, что при применении ее в асинхронных генераторах автономных источников электроэнергии она создает напряжение одной величины.A disadvantage of the known winding is that when it is used in asynchronous generators of autonomous sources of electricity, it creates a voltage of one magnitude.
