The assembly has stator (20) equipped with stator coils (25) and rotor (21) housed inside an enclosure (1, 7) and a bearing device (4) supporting the rotor. The stator is formed as a multi-pole thin ring with a set of teeth (3) that is formed by pressing a ferromagnetic powder into a tooth shape. The coils are embracing one tooth at a time which provides the rotor to have a pole pitch slightly different from stator slot pitch. |
