Locked rotor test
鎖定轉子試驗 -
Firstly, the experimental phase current and input power data obtained from load test are employed to estimate the parameters in ii rated condition. then, the phase current and input power data in locked rotor condition are used to track the variation of the parameters of the secondary coil with slip frequency. the classical method and the direct modification method are also used to estimate the parameters of the induction machine in comparison with this technique
首先利用了負載試驗的定子電流和輸入功率數據來識別額定工況下的電機參數，然後又使用了堵轉時的定子電流、輸入功率數據來識別電機二次繞組參數隨轉差頻率的變化，並與傳統參數測試方法和直接修正參數法進行了比較。 -
