An electric motor comprising: a stator ; an armature rotatably received within the stator, the armature having an armature shaft on which a commutator is mounted; and a brush assembly comprising: a brush card mount disposed around the commutator; a brush holder mounted on a surface of the brush card mount; a brush disposed within the brush holder in sliding contact with the commutator to supply electric current to the commutator; a spring post projecting from the brush card mount; a torsion spring having a wound portion secured around the spring post adjacent the brush holder, and having a leg arranged to engage a back surface of the brush; and a spring stop post disposed proximate an outer periphery of the brush card mount, substantially adjacent the leg of the spring , the spring stop post being circumferentially located between the spring post and the brush holder within an angle formed between the brush holder and the spring post relative to a center of the brush card mount, to limit an outward movement of the leg of the spring away from the back surface of the brush , wherein the spring stop post is engageable with a middle portion or distal end of the leg of the spring. a stator ; an armature rotatably received within the stator, the armature having an armature shaft on which a commutator is mounted; and a brush assembly comprising: a brush card mount disposed around the commutator; a brush holder mounted on a surface of the brush card mount; a brush disposed within the brush holder in sliding contact with the commutator to supply electric current to the commutator; a spring post projecting from the brush card mount; a torsion spring having a wound portion secured around the spring post adjacent the brush holder, and having a leg arranged to engage a back surface of the brush; and a spring stop post disposed proximate an outer periphery of the brush card mount, substantially adjacent the leg of the spring , the spring stop post being circumferentially located between the spring post and the brush holder within an angle formed between the brush holder and the spring post relative to a center of the brush card mount, to limit an outward movement of the leg of the spring away from the back surface of the brush , wherein the spring stop post is engageable with a middle portion or distal end of the leg of the spring. a brush card mount disposed around the commutator; a brush holder mounted on a surface of the brush card mount; a brush disposed within the brush holder in sliding contact with the commutator to supply electric current to the commutator; a spring post projecting from the brush card mount; a torsion spring having a wound portion secured around the spring post adjacent the brush holder, and having a leg arranged to engage a back surface of the brush; and a spring stop post disposed proximate an outer periphery of the brush card mount, substantially adjacent the leg of the spring , the spring stop post being circumferentially located between the spring post and the brush holder within an angle formed between the brush holder and the spring post relative to a center of the brush card mount, to limit an outward movement of the leg of the spring away from the back surface of the brush , wherein the spring stop post is engageable with a middle portion or distal end of the leg of the spring. <EOS>
