Abstract
Magnetic cores including a bonding material having magnetic filler therein is disclosed, as well as devices including the same. The magnetic cores may have superior magnetic properties or adopt the benefits of both soft magnetic composite cores and laminate cores. The magnetic cores disclosed herein exhibit greater relative magnetic permeability in the normalized direction as well as greater saturation flux density.
Claims20
A lamination core comprising:
- a stack of iron-containing sheets;
- and
- an adhesive between the iron-containing sheets, the adhesive including a resin and a magnetic filler.
An electric machine comprising:
- steel laminations;
- and
- a bonding material between the laminations, the bonding material including an epoxy resin and a magnetic filler dispersed therein.
An electric machine comprising:
- a first component having a first magnetic core including first laminations and a first adhesive therebetween, the first adhesive including a first resin such that the first magnetic core has a 2-D magnetic flux path;
- and
- a second component having a second magnetic core including second laminations and a second adhesive therebetween, the second adhesive including a second resin and magnetic filler such that the second magnetic core has a 3-D magnetic flux path.
