KEB line chokes provide input impedance which helps reduce
harmonic distortion and increase VFD component lifetimes.

 

KEB load reactors help reduce dv/dt switching peaks and increase motor life. 

OPTIONS

Line Choke

A line reactor is placed at the input side of a VFD. The added impedance improves the drives harmonic current distortion level.

Motor Choke

A motor reactor is placed at the output of a VFD. It reduces the dV/dt levels of the PWM switching and increases motor operating lifetime.

dV/dt Motor Chokes

Specially designed dV/dt motor chokes are available for installations where the motor is mounted a significant distance away from the VFD (> 40 feet).

KEB dV/dt chokes are capable of being used with up to 16kHz switching frequency and have low inductances for use with PM servo motors.
