LINE REACTORS
Utillizing variable speed drives to control motor speed has impacted the industry both in energy savings and increased efficiencies. The challenge for today's designers is dealing with non-linear wave shapes generated by solid state devices.
By choosing a HPS line reactor, many line problems can be eliminated. Additionally, performance, life expectancy and efficiency of both the motor and the drive itself are significantly enhanced.
HPS offers two lines of Line Reactors:
RM Line Reactor
Due to the attenuation of line disturbances, the life of your solid state devices are extended when protected by the use of a HPS line reactor. Line reactors, when selected for the output of your drive, will enhance the waveform and virtually eliminate failures due to output circuit faults. Subsequently, motor operating temperatures are reduced by 10 to 20 degrees and motor noise is reduced due to the removal of some of the high frequency harmonic currents.
HPS Line Reactors can:
-
Eliminate nuisance tripping
-
Extend the life of switching components
-
Extend the life of your motor
-
Minimize harmonic distortion
-
Short circuit capability
-
Reduce line notching

RC DV/DT Filter
The HPS RC series DV/DT filters are specifically designed for drive/motor applications with long lead lengths (usually where the motor cable length is 20 feet and greater). They should always be installed next to the IGBT variable frequency drive. Typical installation applications include production process lines, conveyor systems and deep wells.
The RC series DV/DT filters combine appropriate values of inductance, capacitance and resistance to form a filter which reduces DV/DT and peak voltages from the PWM voltage waveform. When combined with a 3% impedance reactor that will reduce motor heating harmonics, the life of the motor will significantly increase.
