Sinusoidal Filter

Sinusoidal Reactor（SWL）Sine Wave Filter

1Product Description

   Convert PWM output signals of the motor into a smooth sine wave with low residual ripple voltage to prevent damage to the motor's winding insulation. Reduces the resonance caused by distributed capacitance and inductance due to long cable lengths; eliminates motor overvoltage caused by high dv/dt; reduces early motor failure caused by eddy current losses; the filter lowers the audible noise of the motor.

     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.

2Product Features  

Utilizes a high-performance foil winding structure with copper busbars, featuring low direct resistance,

High electromagnetic resistance; strong short-term overload capability.

Utilizing high-performance composite insulating materials of F-grade or above.

Maintain reliable performance under harsh working conditions.

The reactor has high insulation strength and can withstand extremely high voltage spikes of Dv/dt.

The reactor uses vacuum pressure impregnation technology, featuring low audible noise.

     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.
