This paper presents an analytical model of U-shape tooth-coil-winding modular permanent magnet synchronous machines (TCW-MPMSMs) in terms of main design parameters. Analytical expressions for the flux ...

We made small superconducting coils and measured the total AC loss under the AC and DC external magnetic fields. The coil winding conditions are that 1, 5, and 10 N of the winding tensions and bobbin ...
