As a result, it has been found that the electromagnetic force is easily applied to the rotor 12 evenly, and deformation of the rotor 12 of the generator 1 is suppressed. As a result, it has been found that vibration caused by the deformation of the rotor 12 is suppressed.

Abstract

La présente invention a trait à une machine électrique tournante (1) qui est dotée d'enroulements (15) qui sont enroulés avec des enroulements concentrés autour des dents (14) d'un stator (11). La machine électrique tournante est conçue de manière à ce que le nombre de fentes par pôle par phase (q), qui correspond à une valeur qui est calculée en divisant le nombre (Ns) de fentes (13) par le nombre de pôles magnétiques (P) et le nombre de phases de tension (m), est une fraction qui satisfait la relation 1/4 < q < 1/2, tandis que la partie d'enroulement d'un enroulement est agencée dans une fente.
