  • Publication number: 20200258663
    Abstract: According to an embodiment, a composite permanent magnet includes a matrix of magnetically hard phase grains having an average grain size of 10 nm to 50 ?m; and magnetically soft phase grains embedded within the matrix, and having an average grain size of at least 50 nm, each grain having an elongated shape with an aspect ratio of at least 2:1. According to another embodiment, a composite permanent magnet includes a matrix of magnetically hard phase grains having an average grain size of 10 nm to 50 ?m; and magnetically soft phase grains embedded within the matrix, and having an average grain width of at least 50 nm, an average grain height of 20 to 500 nm, and an aspect ratio of at least 2:1. According to yet another embodiment, a method of forming a composite permanent magnet is also provided.

  • Publication number: 20190148994
    Abstract: Magnetic cores and methods and fixtures for forming the same are disclosed. The magnetic core may comprise a magnetic body including magnetic grains and a magnetic flux path, the magnetic grains are aligned in a plurality of distinct directional alignments to conform to the magnetic flux path. The grain orientation of the cores may be provided by fixtures including electrical circuits and/or permanent magnets. The fixtures may be configured to produce magnetic fields that approximate, mimic, or correspond to a magnetic flux path in the magnetic core, once it is consolidated and in use. The magnetic fields may orient the grains of the magnetic core when they are in an unconsolidated state, such that the grains are aligned in a plurality of directional alignments that approximate, mimic, or correspond to a magnetic flux path in the magnetic core.
