U.S. Patent and Trademarks Office granted OnFILTER a U.S. Patent 10,263,591 "DEVICE AND METHOD FOR REDUCTION OF ELECTRICAL NOISE FROM PULSED SIGNAL DEVICES" which, among other things, addresses unique configuration and design of OnFILTER' filters for pulse-width modulation (PWM) motors. Our motor filters improve reliability of PWM motors by reducing bearing damage caused by EMI leakage currents. The filters also reduce overall EMI levels in equipment improving tool's up-time and precision and controlling electrical overstress (EOS) to sensitive devices.
OnFILTER' servo filters offer a unique advantage over traditional attempts to control EMI problem:
> Unlike mechanical contacts and brushes, our filters have no mechanical parts and require special installation or maintenance.
> Unlike mechanical contacts or brushes, our filters are very effective in suppressing overall EMI.
> Unlike conventional reactors our filters reduce leakage currents 50 to 100 times or more, not merely 2...3 times.
> Unlike conventional reactors we offer unique combo filter combining both motor and AC filtering in one small and effective package saving space and cost while improving performance
