Ki jan yo chwazi frekans aktyèl la lè gwo fou a chofaj endiksyon chofe tiyo a asye?
Ki jan yo chwazi frekans aktyèl la lè gwo fou a chofaj endiksyon chofe tiyo a asye?
Endiksyon chofaj gwo founo dife chofaj tiyo asye se jeneralman nan chalè, Se poutèt sa, lè chwazi frekans lan, eta a cho aktyèl chalè D yo ta dwe pi gran pase epesè nan miray la tiyo.
Tablo 2 -. 8 montre endiksyon solenoid chofaj tiyo an asye ak asye frekans optimal, ak tab 2.9 lis (pi wo a pwen an Curie) chofaj epesè miray tiyo asye a jwenn pi bon efikasite ki pi wo a lè frekans divès kalite.
