Project information 


By adding the filter to the motor the peaks are suppressed.

Left is a picture of voltage on the motor terminals when using

80 meters of cable. The voltage spikes are 1220 V.

On the right the motor filter is added to the motor.

The peaks are suppressed and voltage limited to 624V.


Motor Surge filter         

Frequency inverters and long motor cables.

Motor terminal voltage without filter raise to 1.22 kV.

Motor terminal voltage is limited to 624 Volts when filter is applied.
