Abstract

L’invention concerne une machine électrique à bobinage torique (100) comprenant : un rotor (102) comportant P≥1 paire(s) de pôles magnétiques, et un stator (120) comportant un bobinage torique ; caractérisé en ce qu’il comprend en outre un dispositif (130) de détection de court-circuit dans ledit bobinage torique, comprenant au moins un circuit de détection (132) formé par B≥2 de bobines toriques (134,136), dites bobines auxiliaires, disposées autour dudit stator (120) : lesdites bobines auxiliaires (134,136) étant reliées entre-elles en série ; deux bobines auxiliaires adjacentes (134,136) étant séparées d’un angle géométrique β tel que : , avec k un entier relatif ; de sorte que en l’absence de court-circuit dans ledit bobinage torique, la tension aux bornes dudit circuit de détection est nulle. Figure pour abrégé : Fig. 1A toroidal-wound electrical machine (100) comprising: a rotor (102) having P≥1 pair(s) of magnetic poles, and a stator (120) having a toroidal winding; characterized in that it further comprises a short-circuit detection device (130) in said toroidal winding, comprising at least one detection circuit (132) formed by B≥2 of toroidal coils (134,136), called auxiliary coils , arranged around said stator (120): said auxiliary coils (134,136) being connected together in series; two adjacent auxiliary coils (134,136) being separated by a geometric angle β such that: , with k a relative integer; so that in the absence of a short circuit in said toroidal winding, the voltage across said detection circuit is zero.
