Abstract
The invention provides a commutator motor capable of reducing vibration and noise generated in commutator motor and improving durability against breakage of armature. A commutator 3 having a conductive section 32 mounted on a rotary shaft 1 through an insulating section 31 is provided with a vibration-isolating member 33 made of rubber by adhesion or integral formation at the location between the conductive section 32 and the rotary shaft 1, for example, between the insulating section 31 and the rotary shaft 1 or between the conductive section 32 and the insulating section 31. In one aspect of the invention, another vibration-isolating member supports a brush holder 4 for holding a brush 41 coming in contact with the commutator 3.
Claims6
