Reactors & Filters

Increase motor life expectancy

Installing an output reactor or  lter can

increase motor life and performance in

many applications.

APPLICATION

Variable frequency drives produce voltage spikes that are a function
of voltage rise time and length of motor cable. In extreme cases, peak
voltages may exceed three times nominal operating voltage. Ideal for
use with PENTEK PPC3 and PPC5 Pump Controllers.

REACTORS AND FILTERS

A reactor is a resistance and inductance device that reduces
the voltage spikes. This is accomplished both by increasing the
voltage rise time as well as by improving the impedance match
of the motor and cable.

A  lter combines a reactor with a capacitor network. The capacitor
network absorbs a portion of the voltage spike, further reducing the
peak voltage seen by the motor.

WHEN TO USE A REACTOR AND FILTER

The chart below will provide some guidelines as to when to use a
reactor or  lter. Careful considerations should be given when:

►

Long motor lead lengths are used

►

Using NEMA standard, premium efficiency, submersible motors

►

Quality and age of the motor are unknown

►

Using a submersible motor over 230V

►

The cost of replacing the motor is prohibitive

►

Consistency of environment and/or power quality is unknown
