The sine-wave filter installs at the inverter output and converts PWM voltage into a smoother motor waveform. It reduces dv/dt, motor overvoltage, cable-related capacitance and resonance, eddy-current loss and audible motor noise.
The captured design uses foil windings, copper-bar terminals, F-class or higher insulation and vacuum pressure impregnation. Select a 380V model by motor power, rated current, dimensions and cable/application conditions.
