Abstract

Dans le circuit décrit, un circuit électrique du rotor est relié à une première et une seconde bague collectrice, chacune de celles-ci coopérant avec des balais connectés électriquement à une source de courant, et d'autre part, un interrupteur-inverseur est branché en série. Le circuit du rotor possède les bobines des pôles, qui sont reliées à l'une des bagues collectrices et qui, grâce à l'insertion d'une première diode, sont reliées avec le circuti électrique des enroulements polaires ne devant pas être commutés, le circuit étant pourvu d'une deuxième et d'une troisième diode. Le circuit électrique est fonctionnellement relié à une autre bague collectrice. En outre, il est prévu une ramification de lignes qui possède une quatrième diode à polarité inverse de celle des diodes précitées. Une connexion des diodes est prévue entre les enroulements polaires devant être commutés et la première diode; l'autre connexion de diode est prévue entre les enroulements ne devant pas être commutés et la deuxième diode.
