Sine-wave Filters

Sine-wave Filters reduce motor insulation stress and switching acoustic noise from the motor. Bearing currents are also reduced, especially in larger motors.

The perfect solution for:
* Applications with older motors
* Aggressive environments
* Applications with frequent braking

Range
3 x 200 – 500 V
3 x 525 – 690 V

Advantages:
* Protects the motor against dU/dt stress which prolongs the lifetime
  * Lower the frequency depending losses in the motor, eddy current losses and stray flux losses
* Diminishing acoustic switching noise on the motor
* Reduces semi conduct losses in the drive with long motor cables
  * Decrease electromagnetic radiated emissions on unshieldedmotor cables
* Reduce voltage peaks
  * Reduce electrical discharges in the motor construction thus prolonged bearing lifetime
