1.  產(chǎn)品簡述 (Product Pro?le)

 將電動機的PWM輸出信號轉(zhuǎn)化為低剩余紋波電壓的光滑正弦波，防止對電機的繞組絕緣造成損害。減少了因電纜線長而出現(xiàn)的分布電容和分布電感產(chǎn)生共振的現(xiàn)象;消除高dv/dt而造成的電機過電壓;消除渦流損耗造成的電動機提前損壞;濾波器降低了電動機的可聽噪音。

    Sinus Filter is designed to convert the PWM output signal of motor drives into a smooth sine wave with low residual ripple so as to avoid the motor insulation damage,reduce the resonance phenomenon caused by thedistributed cap6acitance and inductance due to the long cable, eliminate the excessive motor voltage caused by high dv/dt,eliminate motor damage caused by eddy loss and reduce the noise of motor by ?lter application.

2.產(chǎn)品特點 (Product Features)  

  采用了高性能的箔式繞組結(jié)構(gòu)，銅排引出，具有直流電阻小，抗電磁力能力強，短時間過載能力強；采用高性能的F級以上的復(fù)合絕緣材 料，使產(chǎn)品在嚴(yán)酷的工作條件下依然可以保持可靠的性能；電抗器絕緣強度高，能承受極高的Dv/dt的電壓沖擊。電抗器采用真空壓力浸漬工藝，可聽噪音小。

    Due to the excellent foil winding structure and aluminum leading structure, Sinus Filter is characterized by small DC resistance, strong resistance to electromagnetic interference and strong short-time overload capability. F Class insulation materials equip the products with reliable performance even in harsh operating conditions;high insulation ability can sustain high Dv/dt voltage impulse to the reactor; process makes the humming noise low.
