Electromotive turning device for internal combustion engines with a pinion that can be engaged and disengaged.
In the case of electric starting motors for internal combustion engines, this is on the. Steel pinion seated on the armature axis becomes magnetic after a short time due to the influence of the electric motor.
It is now when the pinion is engaged by a two-stage circuit of the cranking motor. the pinion being engaged in the first gear stage by a weak current and automatically the second gear stage after full or partial engagement. d. H. the full

This would make it possible to eliminate this deficiency. that the starting motor is given larger field magnets in order to exert a stronger excitation of the same and such a strong axial thrust on the armature or the pinion that its full shoe and thus the switching on of the full working current is safely achieved.
