Input line chokes in drive and automation technology
TRAMAG products explained
Line chokes are used in variable speed drive solutions and are installed between the line input and the frequency inverter.
Their most important function is to protect the inverter input side. Input line chokes are used to dampen harmonic currents in the input and to allow commutation time for the frequency inverter’s fast-switching switching elements. Line reverse effects caused by commutations are thereby limited. In this way, the availability and safe operation of the drive solution can be constantly maintained.
The connection technology for this application is based on fixed busbars, which significantly simplify installation in the control cabinet environment.
TRAMAG line chokes are already used worldwide in a wide variety of drive systems. Thanks to our many years of experience in the development and manufacture of chokes, we can find the right solution for every application – including yours!

Sinusoidal Filters for drive systems with special requirements
TRAMAG chokes and filters are used in drives systems whose core component is a frequency converter that controls one or more motors of a machine or system. Between frequency converters and motors, caused by long cable lengths, undesirable voltage surges can occur at the motor terminals and damaging, parasitic losses can occur in the motor.More
