產品詳情資料：

當電機運行時，轉子以接近同步的速度沿正序電流的方向旋轉。負序電流的相位旋轉與正序電流相反（因此，與轉子旋轉相反），產生轉子電壓，產生大量轉子電流。該感應電流的頻率約為線路頻率的2倍：50Hz係統為100Hz，60Hz係統為120Hz。在該頻率下，轉子棒中的趨膚效應導致轉子電阻***增加，因此轉子加熱***增加。電機制造商提供的熱極限曲線中未考慮這種額外的加熱，因為這些曲線僅假設電源和電機設計完全平衡的正序電流。

產品英文詳情資料：

When the motor is running, the rotor rotates in the direction of the positive-sequence current at near synchronous speed. Negative-sequence current, with a phase rotation opposite to positive-sequence current (and hence, opposite to the rotor rotation), generates a rotor voltage that produces a substantial rotor current. This induced current has a frequency approximately 2 times the line frequency: 100 Hz for a 50 Hz system or 120 Hz for a 60 Hz system. The skin effect in the rotor bars at this frequency causes a significant increase in rotor resistance and therefore a significant increase in rotor heating. This extra heating is not accounted for in the thermal limit curves supplied by the motor manufacturer, as these curves assume only positive-sequence currents from a perfectly balanced supply and motor design.
