摘要：

High-temperature superconducting (HTS) dynamo magnetic flux pumps are perspective devices for contactless charging the superconducting magnets and coils. Using a thin-shell model of a coated conductor with a ferromagnetic substrate and a Chebyshev spectral method for numerical solution, we show that such a substrate increases the pump-generated voltage if the superconducting layer is between the rotor and the substrate. For the opposite conductor orientation, the voltage decreases. We also demonstrate that the main substrate-depending pump characteristics can be extracted from solutions to problems with a given transport current and then used in a simple analytical description of charging a coil.
