正弦波电抗器（SWL）Sine Wave Filter

1、产品简述 (Product Profile)

   将电动机的PWM输出信号转化为低剩余纹波电压的光滑正弦波，防止对电机的绕组绝缘造成损害。减少了因电缆线长而出现的分布电容和分布电感产生共振的现象;消除高dv/dt而造成的电机过电压;消除涡流损耗造成的电动机提前损坏;滤波器降低了电动机的可听噪音。

     Sinus Filter is designed to convert the PWM output signal of motor drives  a smooth sine wave with low residual ripple so as to avoid the motor insulation damage,reduce the resonance phenomenon caused by the distributed capacitance 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 filter application.

2、产品特点 (Product Features)  

采用了高性能的箔式绕组结构，铜排引出，具有直流电阻小，

抗电磁力能力强，短时间过载能力强；

采用高性能的F级以上的复合绝缘材料，

使产品在严酷的工作条件下依然可以保持可靠的性能；

电抗器绝缘强度高，能承受极高的Dv/dt的电压冲击。

电抗器采用真空压力浸渍工艺，可听噪音小。

     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.
