Motor Choke N CNW 854

Three-phase motor choke

DESCRIPTION

NEW SERIES!

The new series not only scores points for its faster delivery time, but also for its resource conservation and increased efficiency.

Reduce voltage rise (< 200V / µs) and distortions – optimally protect electrical consumers.

In addition to voltage rises, there is a considerable amount of symmetrical and asymmetrical current distortions generated at the motor supply line due to the rapid switching of power semiconductors. These become more pronounced with increasing cable length. These disturbances can affect the motor’s performance through loud noises and, in extreme cases, through overheating. A motor choke can provide a remedy here. The motor choke reduces the voltage rise and voltage peaks between the conductors. Furthermore, the current is smoothed.

Losses and heating are minimized and leakage current is reduced. Longer motor cable lengths can be used. The motor insulation is protected, thus increasing its lifespan. The motor choke also dampens conducted interference in the lower frequency range very well. Losses and typical noises in the motor laminations are reduced. Voltage rises are reduced to (< 200V / µs.)

Increasing the service life of motors, lowering the edge steepness du / dt to earth and between the phases, reducing motor noise, and current smoothing.
