Patent number: 6680596Abstract: An electric motor having a regenerative braking capability is described which has several embodiments, each of which utilize two pairs of brushes, each pair of which has individual brushes positioned on diametrically opposite sides of the commutator. One pair is positioned for preferably optimally running the motor while the other pair of brushes is used solely for braking purposes. For normal motor or running operation, a motor switch assembly interacts with an activating mechanism to physically lift the pair of braking brushes from the surface of the commutator and also ensures that the running brushes come into contact with the commutator. When the motor switch assembly is switched to stop the motor, the switch assembly causes the activating mechanism to first lift the running brushes from the surface of the commutator and then place the braking brushes onto the commutator surface.Type: GrantFiled: October 10, 2002Date of Patent: January 20, 2004Assignee: S-B Power Tool CorporationInventor: John DeCicco
