Abstract:
A starter device for internal combustion engines, comprising a starter motor; a current measuring module which measures a starter current of said starter motor, said starter measuring module including a magnetic field sensor; control electronics controlled by said magnetic shield sensor and generating a control signal for switching off said starter motor when a switch-off current of said starter motor is reached; a conductor carrying said starter current, said current measuring module including a soft-iron core which at least partly surrounds said conductor, said soft-iron core having a through-opening which is greater than said conductor so that a coaxial ring gap remains between said soft-iron core and said conductor, said magnetic field sensor being arranged in said coaxial ring gap; and a starter relay which has a contact bolt which forms said current-carrying conductor, said starter motor has an electrical connection contact; and further comprising a fastener which locks said current measuring module and simultaneously clamps an electric connection between said contact bolt of said starter relay and said electrical connection contact of said starter motor.
