Motor reactors

Function
Motor reactors have higher inductance than dv/dt limiting reactors thus they effectiveness in voltage steepness and peak value reduction is much better. ED3S reactors are a good choice when medium motor cables are used and protection against EMC disturbances is important for the application.

Benefits	Application
Reduction of the steepness of voltage rise dv/dt Limitation of the amplitude of the overvoltage at the motor terminals Decrease in motor temperature Increase in reliability and motor lifetime Decrease of motor noise and EMC disturbances	AC drive systems with frequency converters AC motors with lowered insulation strength Motor cables of medium length
