  Elektromotorische Andrehvorrichtung für Verbrennungskraftmaschinen mit   ein-und ausrück-   barem Ritzel. 



   Bei elektrischen Andrehmotoren für Verbrennungskraftmaschinen wird das auf der. Ankerachse sitzende Stahlritzel durch den Einfluss des Elektromotors nach kurzer Zeit magnetisch.

  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
