I am having problems with a Bodine permanent magnet DC drive 1/4 hp 130 vdc SCR drive putting noise on its 120VAC supply power supply. This noise is effecting some sensitive equipment being fed by the same 120VAC source. I have tried some low cost EMI/RFI filter we had on hand on both
the sensitive equipment and on the motor control board but this did not help. An isolation transformer to just feed this motor control did eliminate the problem but is an expensive solution in time and cost. Can anyone recommend an appropriate filter or approach?
Thanks.
