4 потери на вихревые токи
потери на вихревые токи
Потери на вихревые токи. В проводящей среде за счет ЭДС самоиндукции, пропорциональной скорости изменения магнитного потока, возникают вихревые токи. Вихревые токи нагревают проводники, в которых они возникли. Это приводит к потерям энергии в магнитопроводах (в сердечниках трансформаторов и катушек переменного тока, в магнитных цепях машин). Для уменьшения потерь на вихревые токи необходимо использовать материал с повышенным удельным сопротивлением, либо собирать сердечник из тонких слоев, изолированных друг от друга.
