Method of manufacturing a transverse flux electrical machine rotor

The present invention provides cancellation of cogging torque of a permanent magnet electrical machine using two sets of magnetic elements, one set is mechanically coupled to the stator with the other set being mechanically coupled to the rotor of the machine. At least one of the two sets has permanent magnets with the magnetic elements of the other set being made of permanent magnets or non-magnetized ferromagnetic materials such as soft iron. When the arrangement of the elements of the two sets is properly designed, magnetic attraction and repulsion forces between the magnetic elements of the two sets produces, as the machine operates, an anti-cogging torque which substantially cancels the cogging torque of the machine.
