The Roxburgh filters differ in the number of stages. The MDF (Motor
Drive Filters) filters are single stage filters; the MIF (Motor Inverter
Filters) filters are three-stage filters. The three-stage filter will remove
more of the noise, but the cost is more panel space in the higher
current filters. In the lower current filters (<50 A), the panel space
used is less for the MIF filters.
The Schaffner filters are single-stage filters. These differ from the
Roxburgh filters in component types, values and placement. The
leakage current is generally lower, but the amount of attenuation is
lower too. These filters will work if the amount of noise in the
environment is low, or if the design of the machine is such that only a
nominal amount of attenuation is needed.
Basic guidelines for reducing electrical noise and increasing
electromagnetic compatibility (EMC) are listed in Appendix E,
“Electromagnetic Compatibility Guidelines for Machine Design”.
