4.1.6 Magnetic Ring and Buckle
Model
The magnetic ring is mainly used on the input side or output side of the AC drive.
Install it as close to the drive as possible. When it is installed on the input side, the
noise in the input power supply system of the drive can be suppressed. When it is
installed on the output side, the interference generated by the drive to external
devices can be suppressed and the bearing current can be lowered.
The magnetic ring or buckle can also be used to suppress the leakage current or other
signal cable interference in some applications.
● Amorphous magnetic ring: high permeability when within 1 MHz, good
suppression of drive interference, but high cost
● Ferrite magnetic buckle: good performance when in the frequency band above 1
MHz, suppression of interference noise of various signal cables, low cost, and
convenient and neat for installation
