Method for fabricating a highly-dense powder iron pressed stator core for use in alternating current generators and electric motors |
摘要 |
A high-density stator core for use in electrodynamic devices is fabricated by the electromagnetic pressing of an iron-based powder coated with a dielectric material and methods for performing the electromagnetic pressing are disclosed. The stator core includes a yoke portion that may further include a plurality of integral poles extending either radially outward from an outer circumferential surface of the yoke portion or radially inward from an interior circumferential surface of the yoke portion. The stator core is formed as a near-net-shape compact by an electromagnetic pressing process and has an as-formed density of at least about 98% of the theoretical density.
