7-5 Zero Phase Reactors
You can also suppress interference by installing a zero phase reactor at the main input or the motor
output of the drive, depending on the location of the interference. Delta provides two types of zero phase
reactors to solve interference problems.
A. Casing with mechanical fixed part
Used for the zero phase reactor at the main input/motor output. It withstands large current load and is
used for high frequencies. You can get higher impedance by increasing the number of turns.

, and has high initial permeability, high saturation
induction density, low iron loss and perfect temperature characteristic. If the zero phase reactor does
not need to be fixed mechanically, use this solution.
