Three Phase Line Reactors and DV/DT Filter Reactors
Utilizing Variable Speed Drives to control motor speed has impacted industry both in energy savings and increased efficiencies
Utilizing Variable Speed Drives to control motor speed has impacted 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 Hammond RM series 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.

The Hammond RC series DV/DT filter reactors are specifically designed for drive/motor applications with long lead lengths. They are always installed between the IGBT variable frequency drive and the motor. Typical installation applications include production process lines, conveyor systems and deep wells. The RC series DV/DT filter reactors combine appropriate values of inductance, capacitance and resistance to form a filter, which reduces DV/DT and peak voltages from the PWM voltage waveform. This combined with a 3% impedance reactor that will reduce motor heating harmonics, will significantly increase the life of the motor.
