Patent ID: 7291957

Claim:
A terminal bar structure for a permanent magnet DC motor, the structure comprising: a body structure, a positive terminal bar and a negative terminal bar, each being carried by the body structure, a first ground connection constructed and arranged to electrically connect the positive terminal bar to ground, a first breakable section between the first ground connection and the positive terminal bar constructed and arranged such that when the first breakable section is broken, the connection between ground and the positive terminal bar is terminated, a second ground connection constructed and arranged to electrically connect the negative terminal bar to ground, a second breakable section between the second ground connection and the negative terminal bar constructed and arranged such that when the second breakable section is broken, the connection between ground and the negative terminal bar is terminated, and capacitor structure attached to the terminal bar structure, whereby placement of the capacitor structure and selectively breaking the first breakable section, alone or in combination with the second breakable section, provides selective radio frequency interference (RFI) suppression for the motor.
