This product, adopted pwm integrated circuit and mosfet, igbt that were imported from the overseas, has the following merits : quick - response, strong interfere - proof, stable frequency and voltage, low consumption when light loading, high efficiency and reliable performance, it can be applicable to the family use, pasture region, work with the wind generator and some other places where the power failure often occurs
本品採用pwm （脈寬調制）集成電路和進口大功率mosfet 、 igbt等器件，具有應變快、抗干擾、自動穩定頻率和電壓、空載損耗低、效率高、性能可靠，是家庭，牧區，風力發電機配套以及其它野外經常停電地區提供交流電的必備的電器。These illuminate that voltage vector control of a low power tow phase inverter - fed induction motor driver as a pulse width modulation control of a two - phase inverter - fed induction motor driver system can effectively cancelled the low harmonic and improve the system performance
相對于方波等其它供電方式的控制，採用電壓空間矢量技術在小功率兩相異步電動機的變頻調速控制上的應用可使轉矩脈動減少，效率提高，具有一定的經濟性和實用性。By experiment, we found that the variation of gear case radiant efficiency with frequency keep accordance with that of simple one as a whole, but the radiant efficiency of gear case will go beyond any calculation result of empirical formula when the frequency is below 250hz. we also found that stimulation changes affect radiant efficiency little by varying speed experiment, and it can be ignored in engineering calculation. the rectangle structures as gear case, possess characters of both plane and ball, and their sound radiant efficiency lie between plane and ball region
通過試驗發現，總體上變速箱輻射效率隨頻率的變化規律同簡單構件的輻射效率是一致的，但在250hz以下的低頻區域，變速箱的輻射效率大大高於任何一個經驗公式的計算結果；通過換檔試驗發現，激勵的改變對輻射效率的影響不很顯著，工程計算可以不予考慮；對于變速箱這類三個方向尺寸差別不大的結構，其輻射性質具有平板和球源的雙重特徵，輻射效率介於平板和脈動球源之間，據此提出在工程應用時可以取平板和脈動球源輻射效率的平均作為此類結構輻射效率的觀點。
