摘要： A magnetic circuit, a method of forming a magnetic circuit, a stator (10) or rotor (20) for an electric motor or generator, and an electric motor are disclosed. A magnetic circuit comprises a low reluctance magnetic flux path comprising a plurality of stacked metallic laminations (60,62) (each lamination having an edge (68,74)), and an air gap in operational relationship to at least a portion of the edges (68,74) of the stacked metallic laminations (60,62) (wherein magnetic flux flows at least partially through the stacked metallic laminations (60,62) and the air gap). Adjacent edges (60,62) of the stacked metallic laminations are intentionally offset (H L -H S ).
