A spoke permanent magnet rotor (15) that includes a shaft (30) defining a rotor axis. A first non-magnetic end portion (65) is coupled to the shaft and a ferromagnetic pole piece (85) defines an aperture (105) therethrough. A second non-magnetic end portion (70) is positioned to dispose the pole piece between the first end portion and the second end portion. A portion of one of the first end portion and the second end portion extends through the aperture and bonds with the other of the first end portion and the second end portion.

L'invention porte sur un rotor à aimant permanent à ailettes comprenant un arbre formant l'axe du rotor. Une première extrémité non magnétique est couplée à l'arbre et une pièce polaire ferromagnétique forme dans celui-ci un orifice. Une seconde extrémité non magnétique est positionnée de façon à disposer la pièce polaire entre la première extrémité et la seconde extrémité. Une section d'une partie de la première extrémité et de la seconde extrémité s'étend dans l'orifice et se lie à l'autre première extrémité et à l'autre seconde extrémité.
