?ower Core
Abstract
In most electronic or power cores, silicon iron or electrical steel
laminations are used. This type of lamination causes hysteresis losses
where by heating occurs resulting in losses in power efficiency.
In this invention, a highly efficient Iron Oxide core, Iron Oxide is bonded
together with any suitable resin or plastic or is compacted and enclosed in
a sealed container. The resultant product or products become the core of
any electronic or power device. This core displays low hysteresis losses
because the material instantly responds to a magnetic field and instantly
becomes random when the magnetic field is removed.

Claims

?laims
The embodiments of the invention in which an exclusive property or
privilege is claimed are defined as follows.


1. In the case of any Iron Oxide electric power core comprising of any Iron
Oxide either bonded with resin, plastic or compacted or enclosed in a
sealed or unsealed container with I-100% volume of any Iron Oxide
material.
2. A core as defined in claim 1, that can be easily formed into any
magnetoelectric or electromagnetic shape.
3. A core as defined in claim 1, that is combined, compacted or bonded in
any manner.
4. A core as defined in claim 1, that has low hysteresis losses.
5. A core as defined in claim 1, that will not rust or corrode.
6. A core as defined in claim 1, that has high magnetic permeability.
7. A core as defined in claim 1, that has low heat losses.

,pecif ication
This invention relates to an electromagnetic or magnetoelectric core using
Iron Oxide a~ the core material.
In most electrical core applications, silicon iron cores are used. This type
of core has high hysteresis losses resulting in transformer inefficiencies.
Another popular electronic or power core uses electric steel laminations.
This product has moderate hysteresis losses.
Amorphous metal ribbons have been developed to minimize this hysteresisproblem but cutting the material and forming it into standard transformer
shapes is costly and therefore has not been used widely in the industry
The Amorphous material has rust and corrosion problems.
Disadvantages may be overcome by using any Iron Oxide either bonded
together by plastic, resin or compacted or enclosed in a sealed or unsealed
container to form the core.
This Iron Oxide can easily be made into any shape at much less cost than
Amorphous ribbons, silicon iron or eTectric steel. The material can be
pressed or poured into any desired shape for any electromagnetic or
magnetoelectric application.
The Iron Oxide core demonstrates low hysteresis losses. This feature isevident in that minimal heating occurs in a transformer application under :
load conditions resulting in a highly efficient transformer. This reduces
cooling apparatus requirements in larger applications.
The Iron Oxide core also features very low residual magnetic effects.
No rust or corrosion occurs in the Iron Oxide material therefore extending
the lifespan of the device.
The Iron Oxide core has a high permeability resulting in smaller core
dimensions.
The cores can be used in all electromagnetic or magnetoelectric
applications ie. electric motors, electric generators/alternators, electric
transformers and electromagnets.
