Abstract
Methods are provided for manufacturing a magnetizable core component for use in an electric motor. The method includes forming a green body from a powdered metal-ceramic composite. The method also includes heating the green body to form a core. The method further includes applying a magnetic field to the core to produce paths in a predetermined orientation, where the paths are configured to allow flux to flow therealong. The magnetizable core component is also provided.
Claims18
A method of manufacturing a magnetizable core component for use in an electromagnetic device, the method comprising the steps of:
- forming a green body from a powdered metal-ceramic composite;
- heating the green body to form a core;
- and
- applying a magnetic field to the core to produce the magnetizable core component having paths in a predetermined orientation, the paths configured to allow flux to flow therealong.
A method for manufacturing a magnetizable core component, the method comprising the steps of:
- forming a plurality of green bodies from iron ceramic composite powder having a Curie point;
- simultaneously heating the plurality of green bodies to a first predetermined temperature below the Curie point and bonding at least two of the plurality of green bodies with one another to create a core;
- and
- applying a magnetic field to the core to produce the magnetizable core component having paths in a predetermined orientation, the paths configured to allow flux to flow therealong.
A magnetizable core component manufactured by a method comprising the steps of:
- forming a green body from a powdered metal-ceramic composite;
- heating the green body to form a core;
- and
- applying a magnetic field to the core to produce the magnetizable core component having paths in a predetermined orientation, the paths configured to allow flux to flow therealong.
