ALXION STK永磁無框發電機(Permanent Magnet frameless alternators)解決了風力發電機需要無齒輪 

 

直接驅動以符合成本效益及在低功率 / 中功率需要極高的功率重量比(power-to-weight ratio)的需求。

特點

STK發電機包含一個定子與一個動子,客戶可自行按機構需求組裝。

額定轉速(Rated Speed)80RPM1500RPM

額定功率(Rated Power)200W99KW(取決於尺寸及額定轉速)

・六種直徑尺寸:145mm795mm(內徑自56mm630mm)

・額定轉速和額定負載的標準額定電壓230V

・優異的功率重量比(power-to-weight ratio):高達600W/Kg

・優異的功率體積比(power-to-volume):高達2500W/dm3

 

・不需倍增轉速、不需齒輪機構。

・高可靠度與使用壽命(MTBF高達10萬小時)

・直接驅動具有極高的功率重量比。

・即使在低轉速仍具有高效率(部分型號高達94%效率)  

・具極低的磁性摩擦(magnetic friction)及齒槽轉矩(cogging torque),故在很低的風力

    下即可使STK發電機轉動(只需1%額定轉矩即可轉動發電機)

・簡化機構設計。

・最佳的成本效益。

・此發電機亦可應用水力發電或洋流發電。
