Abstract
An engine starting system that regulates a position of a pinion gear of a starter motor between an engaged position and a disengaged position includes a solenoid pinion armature (SPA) that is coupled to the pinion gear and that is movable between a first position and a second position to move the pinion gear between the disengaged position and the engaged position. A damper dampens a velocity of the SPA during movement of the SPA to the second position to inhibit noise generation.
