Abstract
Embodiments of laminated stator cores suitable for usage in high temperature applications are provided, as are embodiments of methods for manufacturing high temperature laminated stator core. In one embodiment, the method includes obtaining a plurality of coated laminates each comprising a laminate over which a coating precursor layer is formed. The coating precursor layer contain inorganic dielectric particles having a softening point. The plurality of coated laminates are arranged in a laminate stack, which is then fired at temperatures equal to or greater than the softening point of the inorganic dielectric particles. During firing, a compressive force is applied to the laminate stack sufficient to consolidate the inorganic dielectric particles into a plurality of coherent interlaminate dielectric layers electrically insulating and bonding together the plurality of coated laminates as the high temperature laminated stator core.
