RP motor signal magnetic ring manufacturer about the number of turns of the magnetic ring selection

RP motor signal magnetic ring manufacturers tell you that the whole cable through a ferrite magnetic ring constitutes a common mode choke, according to the need, can also be the cable in the magnetic ring above several turns. RP motor signal magnetic ring manufacturers tell you that the more turns, the lower the frequency of interference suppression effect is better, and the higher the frequency of noise suppression effect is weaker. In practical engineering, the number of turns of the magnetic ring should be adjusted according to the frequency characteristics of the interfering current. RP motor signal magnetic ring manufacturers tell you that usually when the interference signal band is wide, two magnetic rings can be set on the cable, each magnetic surround different turns, so that high frequency interference and low frequency interference can be suppressed at the same time. RP motor signal magnetic ring manufacturers tell you from the common mode choke mechanism, the greater its impedance, the more obvious the interference suppression effect.

RP motor signal magnetic ring manufacturers tell you the noise of a fixed frequency, the greater the inductance of the magnetic ring, the better. But this is not the case, because the actual ring also has parasitic capacitance, which exists in parallel with the inductor. When high frequency interference is encountered, the capacitor has a low capacitive reactance, which shorts the inductance of the magnetic ring, thus rendering the common-mode choke ineffective.
