Influence of inter-turn short-circuit fault on the loss of high speed permanent magnet generator with Gramme ring windings

The primary problem brought by high speed is high-frequency loss. The loop current (LC) of inter-turn short-circuit fault causes serious distortion of the magnetic field in high speed permanent magnet generator (HSPMG), whose effects on the loss cannot be ignored. In order to reveal the influence mechanism of ITSC fault on the loss, the two-dimensional finite element model of the 117 kW, 60,000 rp...
