Planar rotor designs for axial air-gap electric machines are presented. Some embodiments comprise rotors each of whose magnetic poles comprise a pair of permanent magnets each magnetized in an orientation of about 45° to the direction of the rotor axis. In some embodiments, axial components of the magnetization of each pair of magnets are co-directional, and tangential components of the magnetization of each pair of magnets are opposite. |
