Abstract:
A solenoid for a vehicle starter comprises a pull-in coil and a hold-in coil positioned axially adjacent to the pull-in coil. A plunger is positioned within the pull-in coil and configured to move in an axial direction when the pull-in coil is energized. The plunger is separated from a plunger stop in the axial direction by an air gap when the pull-in coil and the hold-in coil are not energized. When the pull-in coil and hold-in coil are energized, a shoulder of the plunger moves in an axial direction toward the plunger stop. The pull-in coil is positioned in the solenoid such that it is removed from the plunger stop in the axial direction. In contrast, the hold-in coil encircles the plunger stop.
