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.
