  • Rotor for an electrical machine
    Patent number: 9467014
    Abstract: The present application relates to a rotor (1) for an electrical machine. The rotor (1) comprises at least one substantially cylindrically shaped ferromagnetic base element (2). Said ferromagnetic base element (2) includes a multitude of posts (3, 3.1, 3.2) radially extending therefrom, each of said posts (3, 3.1, 3.2) being bordered by at least a first lateral surface (4) and a second lateral surface (5), wherein recesses (7) are defined between each pair of neighbouring posts (3, 3.1, 3.2). One ferromagnetic intermediate member (13) is arranged in each recess (7) between each pair of posts (3, 3.1, 3.2). Each ferromagnetic intermediate member (13) is affixed to the first lateral surface (4) of a first post (3.1) and to the second lateral surface (5) of a second post (3.2) of each pair of posts (3, 3.1, 3.2) by means of at least one permanent magnet (6, 6.1, 6.2), respectively, said permanent magnets (6, 6.1, 6.2) being each oriented such that the same pole faces said ferromagnetic intermediate members (13).
