Motor Driver Output Reactors are placed between the motor driver and the motor and serve to protect the motor. These reactors stop the motor from over heating by blocking harmonic components created by the motor driver. As a result, motor isolation life lengthens, efficiency of the motor increases and noise decreases. In cases where the motor is feeded through a long cable, high voltages created by capacitive and inductive effects of the cable are prevented by these reactors thus enabeling the motor to work smoothly.

Harmonic filter reactors are serially connected to power condensers found in compensation systems, and protect these condensers against the harmfull effects of harmonics and against a harmonic resonance risk, enabling compensation system to work with no problem.
