SINUS Series

.
Filter for PWM

SINUS

Cod: SINUS

Description

Sinus filters have been specially designed to improve the wave form and avoid overvoltages in the motors. These filters are installed in inverters with PWM output, between the converter and the motor. Switching IGBT (isolated gate bipolar transistor) to high frequency causes an output voltage with peaks that can reach 1300 V (or more) in terminals and coils of the motor. These constant voltage values age the motor and decrease the performance of the coils, also wearing and pitting bearings, causing overheating and unnecessary noises and the transmission of interferences through cables. This effect becomes more obvious the greater the distance between the converter and the motor.
