11-5 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.

initial magnetic 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.

Installation
During installation, pass the cable through at least one zero phase reactor. Use a suitable cable
type (insulation class and wire section) so that the cable passes easily through the zero phase reactor.
Do not pass the grounding cable through the zero phase reactor; only pass the motor wire through the
zero phase reactor. With longer motor cables the zero phase reactor can effectively reduce
interference at the motor output. Install the zero phase reactor as close to the output of the drive as
possible. Diagram A shows the installation diagram for a single turn zero phase reactor. If the wire
diameter allows several turns, Diagram B shows the installation of a multi-turn zero phase reactor. The
more turns, the better the noise suppression effect.
