TRAMAG Sinusoidal Filters, so that Frequency Converters and Motors have a strong and long life
Highlights of the week
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.
The use of TRAMAG sine filters, which are optimally matched to the special drives applications, provides a remedy here. Sinusoidal filters, in combination with chokes as inductance and corresponding capacitors, form a low-pass filter which completely eliminates the voltage peaks and supplies the motor with an almost pure sinusoidal curve with clean mains conditions.
For higher power requirements in industrial applications, e.g. for driving production machines, the motors are operated with three-phase alternating current. The three-phase sinusoidal filter presented today precisely meets this requirement. Designed according to the EN61558-2-20 standard, for a rated current of 1,400A with a rotating field frequency of 160Hz at a clock rate of 2.5 kHz. Equipped with a thermal contact in the V-leg for temperature monitoring by the customer’s installation as well as contact protection against unintentional touching of the front voltage connections for an optimized, reliable functionality of the sine filter in operation.

Participation in the B2Run event on 25. July 2023 in Nuremberg
The weather was kind to the 14,000 runners, who were in the best of moods: Right at the start of this year’s B2Run event around Nuremberg’s Max Morlock Stadium, the rain took a long break. With a pleasant 22º C and a light breeze, a few rays of sunshine even fell on the colorful starting field of employees from many, many companies based in the Franconian region.Learn more
From the Fürth Solar Hill to the own Solar Roof
Eight years after saving the commissioning of the “Fürth Solarberg” with TRAMAG transformers, the Ammon family decided to install their own photovoltaic (PV) system on the roof of TRAMAG’s own company building. The 184kW peak output is sufficient to supply around 55 households with electricity, as reported in December 2011 by the Fürther Nachrichten on the occasion of the commissioning of the TRAMAG PV system, which was also attended by the Mayor of Fürth, who also climbed onto TRAMAG’s roof.Learn more
