Summary: | This electric motor (1) includes a first rotor (10), a second rotor (20), and a stator (30) having 3×n slots provided with windings (33). With the exclusion of a group of even numbers that are obtained by keeping m and n of the numerical expression 2×m+6×n×(k-1) constant and changing k and that include multiples of 3×n/2 as well as the smallest even number and multiples of the smallest even number, 2×i groups are obtained by changing m, and two even numbers are selected, one from the (j+1)th group and one from the (2×i-j)th group respectively, as the number of magnetic poles for the first rotor (10) and the second rotor (20), with i, m, n, and k being integers of 1 or greater, j being an integer between 0 and i-1, and the maximum value of m being 3×n-1.
L'invention concerne un moteur électrique (1) qui comprend un premier rotor (10), un second rotor (20) et un stator (30) ayant 3 × n fentes portant des bobinages (33). À l'exclusion d'un groupe de nombres pairs qui sont obtenus en maintenant constantes les variables m et n de l'expression numérique 2 × m + 6 × n × (k - 1) et en faisant varier k et qui comprennent des multiples de 3 × n/2 ainsi que le nombre pair le plus petit et des multiples du nombre pair le plus petit, on obtient 2 × i groupes en faisant varier m et deux nombres pairs sont sélectionnés, l'un dans le (j+1)ième groupe et l'autre dans le (2 × i-j)ième groupe, respectivement, comme nombre de pôles magnétiques du premier rotor (10) et du second rotor (20), i, m, n et k étant des entiers égaux ou supérieurs à 1, j étant un entier compris entre 0 et i-1 et la valeur maximale de m étant 3 × n-1. |
