Counteracting magnetic field generator for undesired axial magnetic field component of a power generator stator and associated methods

摘要

A power generator ( 20 ) includes a rotor ( 22 ), and a stator ( 23 ) surrounding the rotor and having opposing ends. The stator ( 23 ) includes a stator core ( 21 ) and a plurality of windings ( 28 ) carried by the stator core creating an undesired axial magnetic field component adjacent the opposing ends of the stator. The power generator ( 20 ) may also include at least one counteracting magnetic field generator ( 30 ) associated with at least one end of the stator ( 23 ) for generating a counteracting magnetic field for counteracting the undesired axial magnetic field component.
