The factory s special local product is 3 - phases asynchronous motor with a wound rotor. it is in the lead in domestic market
工廠特色產品是繞線轉子電機其設計工藝質量品種均在國內領先。 -
The observer makes use of motor parameters to estimate speed, but these parameters ( stator and rotor resistance, magnetizing inductance ) will vary because of the change of environmental temperature, iron loss and main flux saturation. so parameter variation will lead to the error of estimation, the purpose of this paper is to study the influence and the compensation of parameter variation
因為觀測器在估計轉速時利用的是電機的額定參數，而電機的參數（定子電阻、轉子電阻、勵磁電感）由於環境溫度的變化、鐵心損耗和主磁飽和的影響將發生變化，所以必然有估計誤差產生。 -
Cause and treatment for cracked terminal lead of generator rotor coil
發電機轉子線圈引出線崩毀原因及處理 -
This model is formulated as a non - linear state - space representation of helicopter flight dynamics, incorporating with blade element unsteady aerodynamics, a finite state dynamic inflow wake model, and flapping / lead - lag blade dynamic model. the formulation of the coupled rotor and fuselage equations enables the use of common solution techniques for trim and linearization in arbitrary steady flight condition as well as control response calculations
本項研究針對新機研製過程必須解決的品質評定、飛控系統設計等問題，按照ads - 33軍用品質規范的要求，建立了一個較完整的直升機非線性的、具有狀態空間表達形式的飛行動力學模型，進行了模型驗證工作，並以某樣例直升機為例，計算了ads - 33品質規范（ 3 -
Also ac exited generator have many excellent characteristics, it may improving the stability of electric power system, its rotor speed may adjustable, it have abilities for active and reactive power regulating in self - help ways, it not lose steps even when operated in deep lead phase, so it especially applied in wind electric power plant and pumped - storage hydraulic power plant
交流勵磁發電機作為發電機運行的風力發電系統，利用變速恆頻技術后可大大提高風能的利用率。交流勵磁發電機可改善電力系統穩定性，轉子轉速可變，具有獨立的有功無功調節能力，可以深度進行運行而不失步，特別適用於風力發電、抽水蓄能電站等場合。 -
The comparison showed that : ( l ) farassat 1a formula is the simplest one and work well for the subsonic rotor. ( 2 ) both kirchhoff formula and k - fwh formula can predict the nonlinear noise generated by transonic rotor ; ( 3 ) when the surface is not positioned in the linear region, kirchhoff approach for rotating integration surface could lead to substantial error, but k - fwh formula can still work well
數值研究表明： farassat1a公式在預測線性噪聲方面簡單有效，適用於亞音速旋翼的噪聲預測； kirchhoff公式和k - fwh公式均能夠預測跨音速旋翼聲場，並且具有較高的精度；當聲源面位於流動非線性時， kirchhoff公式會導致很大的計算誤差，而k - fwh公式不存在這樣的問題。 -
The results of numerical integration predict. that there will be backward whirl of the rotor, which may lead to destructive damage of the system if the back - up bearing has very light or very high damping
數值積分結果預示，當備用軸承具有很小阻尼或很大阻尼時，會導致系統破壞的逆迴旋。
