Zusammenfassung:A method for assembling a direct drive generator assembly includes the steps of placing a rotor over a stator, leaving a gap therebetween. A magnetic hub is assembled using adjacent columns of magnets having opposed orientation, and placed in the air gap. Application of an input torque to generate cogging torque in first direction that offsets coggery torque in second direction.
