Fully encapsulated three-phase motor choke
Description
Reduce voltage rise (< 200V / µs) and distortions – optimally protect electrical consumers. Motor chokes in encapsulated design are specially developed for harsh ambient conditions and offer very good mechanical protection of the component. The encapsulation technology enables protection classes up to IP 66. The motor choke reduces the voltage rise and voltage peaks between the conductors. Furthermore, the current is smoothed. Losses and heating are minimized and the leakage current is reduced. Longer motor cable lengths can be used. The motor insulation is protected, thus increasing the service life. The motor choke also dampens the line-bound interference in the lower frequency range very well. The losses and the typical noises in the motor lamination are reduced. Voltage rises are reduced to ( < 200V / µs ). Increase in the service life of motors, reduction of the steepness of the edges du/dt to ground and between the phases, reduction of motor noises, current smoothing.
