Abstract

Official abstract text for this publication.

A machine ( 1 ) having a rotor ( 11 ) including permanent magnets (PM) and field coils (EC). The magnets are housed in first axial recesses (E 1 ) distributed within a circumferential portion of the magnetic body, thus defining circumferential polar sections. The coils are housed in second axial recesses (E 2 ) distributed within an intermediate portion of the magnetic body. The circumferential polar section includes a third recess (E 3 ), and a portion of the magnetic body forming a bridge having a height of around 0.7 mm to around 2 mm is retained between an apex of the recess and an outer pole face.

First claim

Opening claim text (preview).

The invention claimed is: 1. Rotary electric machine having hybrid-excitation including a stator ( 10 ) equipped with stator coils and a rotor ( 11 ) comprising a plurality of alternate north poles and south poles which are formed from a plurality of permanent magnets (PM) and a plurality of field coils (EC), said permanent magnets (PM) being housed in respective first recesses (E 1 ) extending axially and distributed regularly within a circumferential portion of the magnetic body…
