Description
а под серединой паза - минимальна. Поэтому кривую индукции в зазоре можно представить как результат наложени на. среднюю неизменную пространственную кривую индукции переменной составл ющей.and under the middle of the groove - is minimal. Therefore, the induction curve in the gap can be represented as the result of superposition on. mean constant spatial variable induction curve.
Когда ротор вращаетс , то переменна составл юща индукции оказываетс подвижной относительно ротора и наводит в нем токи зубцовой частоты, вызывающие дополнительпые потери.When the rotor rotates, the variable induction component turns out to be movable relative to the rotor and induces jog frequency currents in it, which cause additional losses.
Величина амплитуды зубцовой переменной составл ющей индукции, а следовательно , потери от нее в роторе сильно завис т от отношени ширины паза статора к величине воздущного зазора, что приводит, в свою очередь, к значительному уменьшению потерь холостого хода.The magnitude of the amplitude of the toothed variable component of the induction, and therefore the losses from it in the rotor, strongly depend on the ratio of the stator groove width to the air gap, which in turn leads to a significant decrease in idling losses.
Так, например, дл турбогенератора типа ТВВ-300 мощностью 300 мВт при 24 пазах статора эти потери состав т 200 кВт, а . при введении предложенных пакетов шихтованной стали, что эквивалентно увеличению числа зубцов статора примерно вдвое, , потери уменьшатс до 30 кВт.For example, for a TBB-300 type turbo-generator with a capacity of 300 mW with 24 stator slots, this loss is 200 kW as well. With the introduction of the proposed packaged steel, which is equivalent to approximately halving the number of stator teeth, the losses will be reduced to 30 kW.
