环形绕组永磁电机短路电流自动抑制分析

Short-circuit faults in permanent magnet (PM) machines have consistently been a hindrance for safety-critical applications. However, short-circuit currents, especially turn-to-turn short-circuit currents, are difficult to detect and suppress in a timely manner. This article investigates the automatically variable impedance characteristics of the toroidal winding, which restricts the turn-to-turn s...
