Abstract

Moteur électrique à courant continu, destiné à être alimenté par un courant haché. Il est agencé de manière que le coude de la courbe représentative du flux magnétique en fonction des ampères tours ait une origine j située, approximativement, au milieu de l'intervalle F d'utilisation du moteur, et la dimension radiale de l'entrefer est suffisamment grande pour que l'accroissement du flux, au-delà de l'origine j du coude, en fonction des ampères tours ait une pente au moins égale à sensiblement le tiers de la pente de la partie linéaire B, qui précède le coude. Application aux moteurs électriques du type série pour la traction de véhicules.
