Abstract:
1. A solenoid for a vehicle starter, the solenoid comprising: a first coil comprised of a first length of rectangular wire forming windings and leads, the first coil a pull-in coil for the vehicle starter; a second coil axially adjacent to the first coil, the second coil a hold-in coil for the vehicle starter, wherein the windings of the first coil are not in contact with windings of the second coil such that the first length of rectangular wire is separated from the second coil except for the leads of the first coil extending in an axial direction across the windings of the second coil; a spool with an internal passage and a middle flange, the first coil and the second coil wound on the spool with the middle flange positioned between the first coil and the second coil, the middle flange separating the first coil from the second coil in the axial direction with substantially no ferromagnetic material positioned between the first coil and the second coil in the axial direction, the middle flange including at least one slot configured to receive a lead of the first coil; and a plunger configured to move in an axial direction within the internal passage of the spool when the first coil is energized.
