Variable core electromagnetic device
First Claim
1. An electromagnetic device, comprising:
- a variable magnetic flux core comprising a plurality of core sections stacked on one another, at least one core section of the plurality of core sections comprising a different selected geometry from other core sections, the at least one core section being configured to provide a predetermined inductance performance in response to the different selected geometry; and
an opening through the stacked plurality of core sections of the variable magnetic flux core for receiving a conductor winding extending through the opening and the variable magnetic flux core, wherein an electrical current flowing through the conductor winding generates a magnetic field about the conductor winding and a magnetic flux flow in each of the plurality of core sections of the variable magnetic flux core, the magnetic flux flow in the at least one core section being different from the other core sections in response to the different selected geometry of the at least one core section to provide the predetermined inductance performance, wherein each of the plurality of core sections comprises a centerline and the opening through the at least one core section comprising the different selected geometry is offset a particular distance from the centerline of the at least one core section that is different from at least one other core section of the plurality of core sections.

Abstract
An electromagnetic device includes a variable magnetic flux core having a plurality of core sections stacked on one another. At least one core section of the plurality of core sections may include a different selected geometry and/or a different chosen material. The at least one core section is configured to provide a predetermined inductance performance. An opening is provided through the stacked plurality of core sections for receiving a conductor winding. An electrical current flowing through the conductor winding generates a magnetic field about the conductor winding and a magnetic flux flow in each of the plurality of core sections. The magnetic flux flow in the at least one core section is different from the other core sections in response to the different selected geometry and/or the different chosen material of the at least one core section to provide the predetermined inductance performance.
