Abstract
A method of providing RFI suppression in a DC motor provides a universal terminal bar structure 70 including a positive terminal bar 72 and a negative terminal bar 76, a first choke 80 electrically connected with the positive terminal bar, a second choke 82 electrically connected with the negative terminal bar, a first ground connection 86 constructed and arranged to electrically connect the positive terminal bar to ground, a first breakable section A between the first ground connection and the positive terminal bar, a second ground connection 88 constructed and arranged to electrically connect the negative terminal bar to ground, and a second breakable section B between the second ground connection and the negative terminal bar. Capacitor structure 90 is attached to the terminal bar structure, and the first breakable section is selectively broken, alone or in combination with the second breakable section to provide versatile RFI suppression.
