ullage rule

To improve the capability of the bearing - less slice permanent motor , to reduce the ullage of the motor and the badly additive torque , i design optimization the structure of the rotor pm , and two projects are proposed . one is four pieces rotor pm which is the same magnetized and the other is eight pieces rotor pm which is different magnetized direction 為了進一步改善片狀無軸承永磁電機的動態性能,減小電機的損耗及有害的附加轉矩,優化設計了轉子永磁貼片的結構,提出了四片同向充磁和八片正反向充磁兩種方案。

A novel bi - directional dc / dc converter was introduced in the dissertation , which based on refer much converter data . the soft switching , phase - shifted pwm and bi - directional dc / dc converter hang together , depress circuit switch ullage and noise effectively , which provide condition to increase switch frequency , efficiency and reduce size and weight for the converter ; at the same , the converter have the virtue of structure compact , voltage and current stress small etc such as ordinary hard switch converter 本文作者在查閱國內外大量雙向dc dc變換器資料的基礎上,采用一種新型雙向dc dc變換器的拓撲結構,把軟開關技術和移相控制pwm技術以及雙向dc dc變換器技術有機結合在一起,有效地降低了電路的開關損耗和開關噪聲,為變換器裝置提高開關頻率、效率以及降低尺寸及重量提供了良好的條件。

Zmd catena of self inhale magnetic force pumps adopt structure of electrical engine direct link form , by centernog prop up , the structure is tightly , teardown and maintenance is convenient , adopt high - powered magnetism stuff nd fe boron to make inside and outside magnet . isolationsheath assembled make of import nonmetallic material , avoid magnetism backset ullage of the run - of - mill pumps have drastically Zmd系列自吸磁力泵采用電機直聯式結構,由中間支架支撐,結構緊湊,拆卸維護方便,采用高性能磁性材料“釹鐵硼”制造內外磁體,隔離套采用進口非金屬材料,徹底消除了一般磁力泵具有的磁渦流損耗,可輸送高濃度,密度大于1 . 84 t m

And experiment was based on the simulation , the results show that charge circuit and uplifted circuit both was adopted the same circuit , which can realize energy bi - directional flow , also have low switch ullage and high dynamic response 在此基礎上進行了實驗研究,仿真和實驗結果表明,該裝置升壓和降壓只采用同一個主電路,即可實現能量的雙向流動,且具有低開關損耗和較高的動態響應。
