In one embodiment, the invention provides an electric motor including an armature, a stator, and brushes. The armature includes an armature winding and a commutator connected to the armature winding. The stator is disposed to magnetically interact with the armature. The brushes are disposed to engage with the commutator to controllably provide electric current to the windings via the commutator. The electric motor further includes an inductor (e.g., a wire-wound inductor) electrically connected in a series relationship with at least one of the brushes and a thermal cutoff device electrically connected in a series relationship with the inductor. The thermal cutoff device is disposed within at least a portion of the inductor.
