A two-pole rotor of increased flux concentration factor employs two pole pieces of magnetic material which are separated from each other by non-magnetic segments. The pole pieces and non-magnetic segments are joined together to form a cylinder with an aperture extending axially through the central portion. Two magnets forming a V shaped configuration and polarized such that the inner faces of the magnets have like polarity are positioned in the central portion of the cylinder with the outer sides of the magnets adjacent to one of the pole pieces. The magnets are located symmetrically about the d axis and asymmetrically about the q axis. The magnets extend above and below the q axis. A prism shaped segment of magnetic material is positioned between the magnets with the base of the prism adjacent to the other pole piece to hold the magnet in place. A stub shaft is mounted on each face of the cylinder.
