6-5 Zero Phase Reactor
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. Due to the large current passed through
the main input/motor output side, pay attention to core saturation issue. Delta provides two types of zero
phase reactors to solve interference problems.
A. Casing with mechanical fixed part
The ideal material for withstanding large current loaded for the zero phase reactor at the main
input/motor output is composite core. Core has strong saturation, and its strong resistance are many
times of simple metal magnetic materials. Thus it can be used for high frequencies and you can get higher
impedance by increasing the number of turns.
