Sine filters

Sine filters effectively protect the motor insulation with frequency inverter drives and thereby extend their lifetime. They reduce supplementary losses and noise emissions from the motor. All-pole sine filters also enable the use of unshielded motor lines. The reduction in common mode currents in the system’s grounding scheme minimizes leakage currents and results in optimum EMC performance for the drive.

Sine filters optimized for performance with Future Winding technology

The sine filter achieves a very high filter effect through precise low pass adjustment to the frequency inverter’s switching frequency. BLOCK sine filters are produced with Future Winding technology and are therefore specifically optimized for performance. They achieve a better cooling effect compared with traditional filters along with lower proximity losses.

Overview:

◼︎  Very high filter effect through precise low pass adjustment
◼︎  Suppression of push-pull interference (Differential Mode)
◼︎  Reduction in edge steepness at standard network level
◼︎  Enables long shielded and unshielded motor supply lines
◼︎  Reduction in leakage currents with compact construction volume
◼︎  Reduction in bearing currents
◼︎  Reduction in motor losses and motor noises
