Description


Voltage rise (<200V / us) and distortion reduce - protect electrical consumers optimally.

In addition to the increase of voltages, there is a considerable amount of symmetric and asymmetric current distortions which are generated at the motor cable through the fast switching of the power semiconductors. These are becoming more pronounced with increasing cable length. These disturbances can affect the performance of the engine by loud noises, and in extreme cases, by overheating. Here, a motor choke remedy. The motor choke reduces the voltage rise and the voltage spikes between the conductors. Furthermore, the current is smoothed.

Losses and heating are minimized and the leakage current reduced. Longer motor cable lengths are possible. By limiting the rate of voltage rise, the motor insulation is protected and thus prolongs the life. The motor choke also attenuates the conducted interference in lower frequency range very good. The losses and the typical noise in the motor plate can be reduced. Voltage rise (<200V / us) will be reduced.

Increasing the service life of motors, reduction of edge steepness dv/dt to earth and between phases, reduce motor noise, current smoothing.
